Answer:
8 weeks
Step-by-step explanation:
First we have jas starting with 145 dollars.
her adds 36 a week to savings.
The total savings we need to get to is 433 dollars.
Let w = weeks needed to get to goal
145 + 36w = 433
Subtract 145 from both sides:
36w = 433 - 145
Simplify:
36w = 288
Divide both sides by 36:
w = 288/36
w = 8
After 8 weeks, jas will have saved 433 dollars.
Check for truth:
145 + 36(8) = 433
145 + 288 = 433
433 = 433 ; check
