Question

Luke is a school student who just started working during the weekend. Mahmoud earns $14 per hour. He would like to buy a game that costs $80 which will have a 13% tax applied to it upon purchase. Luke would like to buy the game but only if he is able to save 30% of the money he will make. How many hours would Luke have to work? Round your answer to 2 decimal places

Answer 1

To find out how many hours Luke would have to work, we need to find out how much money he needs to earn before taxes in order to save 30% of it. The price of the game including tax is $80 + $80 * 13% = $80 + $10.40 = $90.40.

Luke wants to save 30% of this amount, which is $90.40 * 30% = $27.12.

So, the total amount of money Luke needs to earn before taxes is $90.40 - $27.12 = $63.28.

Since Mahmoud earns $14 per hour, Luke would need to work $63.28 / $14/hour = 4.52 hours to be able to save 30% of the money he makes.

Rounded to 2 decimal places, this is 4.52 hours = 4.52 * 1 hour/1 hour = 4.52 hours.
