Aisha · Answer 1

This can be solved by the equation $235 = 8x + 75. To begin subtract 75 from both sides to get 160=8x. With this new equation, divide both sides by 8 to get 20=x or x=20. Since x represents the number of weeks Bill is required to work for the bike, 20 is correct amount of weeks.

To save up enough you will have to take 235-75 which will equal 160 then you take the weekly pay and divide that, it will take 20 weeks.
