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
