Solution

The correct option is B 4 hours
Let Jane plays for x hours.
The amount of money, she have to pay for playing x hours =8+5x
Given that Jane has $28.
8+5x=28
Step 1: Subtract 8 from both the sides of the equation
8+5x8=288
5x=20

Step 2: Divide both sides of the equation i.e. 5x=20 by 5

5x5=205

x=4
Jane can play for 4 hours by spending $28
