Question

The total cost to rent a rowboat is $18 times the number of hours the boat is used. Write an equation to model this situation if C equals total cost and H equals number of hours?

Answer choices -
C-18=h

H=18c

C=h/18

C=18h

Answer 1

If the total cost (C) is $18 multiplied by the hours, it would be C=18h

Answer 2

`C=18h`

Explanation:

Let

C------> represent the total cost

h-----> represent the number of hours

we know that

`C=18h` -----> linear direct variation that represent the situation

In this problem the constant of proportionality k is equal to the slope m of the line

so

`m=18(\$)/(hour)`
