Final answer:
The total cost for two medium coffees and a $12.00 mug is $19.00. Subtracting this from the total $29.00 order, we find that the combined cost for four cupcakes is $10.00. Dividing by four, we conclude that each cupcake costs $2.50.
Step-by-step explanation:
To find the price of each cupcake, we need to do a simple subtraction and division based on the total expenses of the friends' order. They each had a medium coffee costing $3.50, and together, they had four cupcakes. One friend also purchased a mug for $12.00. The total cost of their order was $29.00.
- Cost of two medium coffees: 2 x $3.50 = $7.00
- Cost of the mug: $12.00
The combined cost of the coffees and the mug is therefore $7.00 + $12.00 = $19.00. Subtracting this from the total gives the combined cost of the cupcakes.
Total cost of cupcakes: $29.00 - $19.00 = $10.00 for four cupcakes.
To find the cost per cupcake, we divide the total cost of cupcakes by the number of cupcakes.
Price per cupcake
: $10.00 / 4 = $2.50
Therefore, each cupcake costs $2.50.
