Answer :

We were told that each medium drink costs $1.85 and each large drink costs c more dollars than a medium

drink. This means that

cost of each large drink = cost of each medium drink + c

cost of each large drink = 1.85 + c

If 5 medium drinks and 5 large drinks cost a total of $20.50, it means that

5 * 1.85 + 5(1.85 + c) = 20.5

9.25 + 9.25 + 5c = 20.5

18.5 + 5c = 20.5

5c = 20.5 - 18.5 = 2

c = 2/5

c = 0.4

The correct option is

B) 0.40
