Answer:
The school band will collect $813
Explanations:
Cost of 1 tub of cookie dough = $12
Cost of 1 pack of dry cookie mix = $5
Cost of 1 pack of drop cookie dough = $15
The school band sells:
24 tubs of cookie dough
15 packs of dry cookie mixes
30 packs of drop cookie dough
Cost of 24 tubs = $12 x 24 = $288
Cost of 15 packs of dry cookie mixes = $5 x 15 = $75
Cost of 30 packs of drop cookie dough = $15 x 30 = $450
Total cost = $288 + $75 + $450
Total cost = $813
The school band will collect $813
