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:)
