Question

A local ice cream store is analyzing the day's sales. Each serving came in either a cup or cone, but not both, and the ratio of servings to cups was 7:4. What was the ratio of serving to cones?
A) 4:7
B) 3:4
C) 7:3
D) 11:4

Answer 1

Total servings to cups is 7:4
means total servings is 7 and total cups is 4

total=cups+cones
therefor
cones=total-cups

we want servings to cones

we know that cups=4 units and total =7
we apply
cones=total-cups
cones=7-4
cones=3

cones=3 units

therefor, serrvings to cones is 7:3

answer is C
