Question

you borrow $200 from a friend to help pay for a new laptop computer. You pay your friend back $12per week. Write and solve an inequality to find when you will owe your friend less than $60

Answer 1

Given:
loan = 200
payment per week = 12
should be less than = 60

12x - 200 < 60 
       

12x - 200 < 60
       +200    +200
12x          < 260
 ÷12             ÷12
    x          < 21.67

If x = 20
12x - 200     < 60
12(20) - 200 < 60
240 - 200     < 60
               40 < 60
