Answer 1

Answer: D)3.5h+4

Explanation:

Let h denotes the number of hours that the ice skates are rented.

Since, The cost of renting ice skates is $4 plus $3.50 for each hour that the ice skates are rented.

So , the total cost for ice-skating = $4 + $3.50 x (number of hours that the ice skates are rented.)

= 4+3.50 x ( h) [as expression]

Hence, the expression can be used to find the cost in dollars of renting ice skates for h hours :-

`3.5h+4`
