You borrow $100 from your mom. You repay $5 per week. Write a linear equation to model the situation and find how long it takes to repay the loan.

Answer 1

the base price that you borrowed from your mom is = $100

if we label the number of weeks that have passes as "w", we can create the term "5w" that represents the amount of money you've paid your mom back.

in order to find out how much money you still have to pay your mom, you can subtract 5x (the total you've paid so far) from $100: 100 - 5w

you've paid back your entire loan when 100-5w is equal to 0.

100-5w = 0.

Solving for w:

-5w = -100

w = 20

It would take 20 weeks to repay the loan from your mom.

Answer 2

0 = 100 - 5w

Can you solve for w and answer?
