Q1: Sam wants to buy a new car before he goes to college. His parents said they would pay for half. Sam has been comparing prices and thinks he will find the perfect college vehicle for $18,990. Sam finds a great job sacking groceries at a nearby store making $7.25 per hour. If Sam works 20 hours per week, how long will it take him to save enough money for the car?

65.48weeks

Step-by-step explanation:

Firstly, we know that his parent will pay half of the money

18,990/2=$9495

let us solve for Sam's weekly pay

weekly pay= 20*7.25

weekly pay=$145

Sam earns $145 per week

And the deficit for the car is $9495 (the parent paid half the price)

therefore the number of weeks Sam must work to pay the deficit is

=$9495/145

=65.48weeks

a 10 percent increase
