Question

After the softball game, Alise's coach bought each of the 14 players a double-scoop or triple-scoop ice cream cone at the local ice cream shop. The coach bought a total of 37 scoops of ice cream. Use a model to determine how many girls got a triple-scoop ice cream cone.

A. 6

B. 7

C. 8

D. 9

Answer 1

6

Answer 2

This can be modeled by simultaneous equations. Let x = number of girls with double scoops, y = number of girls with triple scoops.
x+y=15 (because 15 girls total)
x = 15-y
36 = 2x+3y (36 scoops, 2 scoops per double girl, 3 scoops per triple girl)
36 = 2(15-y)+3y (by substituting 15-y for x)
36 = 30-2y+3y
36 = 30+y
y = 6
