Answer: It will take her 7 weeks to save $120.
Step-by-step explanation:
Using the information we can come up with an equation.
If Andre starts with $85 then that will be initial and won't change.She add $5 per week so we could represent that by 5x where x is the number of weeks.
To find how much Ander has saved in total we will represent that by y.
y = 5x + 85 If y is the amount that she has saved over some weeks input 120 in for y and solve for x.
120 = 5x + 85
-85 -85
35 = 5x
x = 7
This means it will take her 7 weeks to save $120.

on the right side u add 5+2=7
then on the right side u add 4k on each side and get rid of the 4k on the right
on the left u subtract 7k-4k=3k
on both sides divide by 3
