Question

The Equation C = 2D shows how the cost of a car ride depends on the distance in miles. The Variable D Represents the number of miles driven, and the Variable C represents the cost in dollars. If a Car ride is 10 miles long, how much will it cost?

A)15
B)30
C)20
D)25

Answer 1

$ 20

Explanation:

Step 1:

Equation is given by C = 2D

Here D is equal to 10 miles

Variable C costs twice the distance traveled.

Step 2:

Here D= 10 Miles.

Hence, C= 2*10 = 20

Hence $20 will be the cost.
