a.

Let x = # of hours

Let y = cost to rent skates

3 + 2x = y

b.

(Plug in 8 for x, because it is the # of hours)

3 + 2x = y

3 + 2(8) = y

(PEMDAS or order of operations)

3 + 16 = y

19 = y

It costs $19 to rent skates for 8 hours.

Answer: 2$ = 1hrs? 16$ for 8hrs

And 3$ = 1hrs? 24$ for 8hrs.

Hope this helps:)
