Kai Cart: Pricing Through a Wet Winter Market
Kai Cart is a family-run food truck that trades every Saturday at a suburban Auckland market. It sells one main product, a chicken wrap. The stall fee is $120 per market day and insurance plus the truck lease totals $80 per day. Two staff work six hours each and are paid $25 per hour including all on-costs, so labour is $300 per day. Ingredients and packaging cost $4.20 per wrap. The current price is $9.00. Average sales are 180 wraps per market day, but the last three wet Saturdays sold 90, 110 and 130. A nearby truck has cut its wrap price to $8.50. Kai Cart can produce up to 250 wraps in a day. The owner is considering matching the $8.50 price or adding a $12.00 wrap-and-drink combo. The combo would add $1.80 of ingredients and packaging to the wrap. The owner wants to keep the business viable through winter, when wet days are more common.
1. Calculate the contribution per wrap and the break-even quantity at the current $9.00 price. Use the average and wet-day sales to assess the margin of safety, and explain what the figures suggest about winter risk.

Fixed costs per market day: stall $120 + insurance/lease $80 + labour $300 = $500.
Contribution per wrap: $9.00 - $4.20 = $4.80.
Break-even: $500 / $4.80 = 104.17, so 105 wraps. Kai Cart must sell 105 wraps just to cover the day.
Average day: 180 x $4.80 = $864 contribution; $864 - $500 = $364 profit. Margin of safety = 180 - 105 = 75 wraps, or 41.7% of sales.
Wet days: 90 wraps gives $432 - $500 = -$68 loss. 110 wraps gives $528 - $500 = $28 profit. 130 wraps gives $624 - $500 = $124 profit. The three wet days average 110 wraps, only 5 above break-even.
The judgement is that the current cost structure is fragile in winter. A small drop in demand turns profit into loss because fixed costs are high relative to contribution. The owner should focus on lowering the break-even point or increasing wet-day demand, not just average-day profit.
2. Evaluate matching the competitor's $8.50 price against keeping $9.00 and introducing the $12.00 combo. Use contribution and volume calculations to support a recommendation.

Option A: match $8.50. Contribution = $8.50 - $4.20 = $4.30. Break-even = $500 / $4.30 = 116.3, so 117 wraps. To match the current average profit of $364, required volume = ($500 + $364) / $4.30 = 200.9, so 201 wraps. That is 21 more wraps than the current 180, an 11.7% increase. It is within the 250 capacity, but on a wet day of 110 wraps the result is 110 x $4.30 - $500 = -$27, still a loss. The price cut only works if it reliably lifts volume by at least 21 on normal days and pushes wet days above 117.
Option B: keep $9.00 and add the combo. Combo contribution = $12.00 - ($4.20 + $1.80) = $6.00. If 40 of 180 customers switch to the combo, contribution = 140 x $4.80 + 40 x $6.00 = $672 + $240 = $912. Profit = $912 - $500 = $412, which is $48 better than now, with no extra customers. If the combo also attracts new buyers, the gain is larger.
Recommendation: keep the $9.00 wrap and trial the combo for four market days, tracking how many customers switch and whether total volume rises. A price cut raises break-even to 117 and demands 201 sales to match current profit, which is risky on wet days. The combo keeps contribution per customer higher and differentiates Kai Cart without starting a price war.
3. Recommend one operational or marketing action, other than price, that Kai Cart could take to protect profit on wet market days. Justify it using the case data and non-financial factors.

Action: use a wet-day staffing and pre-order plan. On days forecast to be wet, operate with one staff member instead of two and promote a pre-order pick-up option to nearby offices and schools.
Financial reasoning: one staff member costs $150 for six hours. Fixed costs become $120 + $80 + $150 = $350. Break-even becomes $350 / $4.80 = 72.9, so 73 wraps. At the observed wet-day level of 90 wraps, profit = 90 x $4.80 - $350 = $82, compared with a $68 loss under two staff. Even at 110 wraps, profit rises from $28 to $178. The saving is $150 per wet day, which matters because wet days are more frequent in winter.
Non-financial judgement: one staff member may slow service and increase stress, so the owner should only do this when pre-orders reduce walk-up demand or when a second person can be called in if a queue forms. Pre-orders also reduce waste because the owner can prepare closer to known demand. This protects the brand better than cancelling the market or cutting portion size, which could damage repeat custom.
