Question

Tina had d dollars. She bought three cupcakes for her and her friends, which cost c dollars each. How much money does she have left after being so nice?

Answer 1

Answer: $(d-3c)

Step-by-step explanation:

Total amount Tina had = $d

Cost of cupcakes = $c

Number of cupcakes purchased = 3

Therefore,

Total cost of cupcakes = cost per cupcake × number of cupcakes

Total cost of cupcakes = $c × 3 = $3c

Amount left after cupcake purchase:

Total amount Tina had - total cost of cupcakes :

$d - $3c
