Answer: Equation: 70w + 550 = s
let w = weeks
let s = total amount of money in savings
Total amount of money after
11 weeks: $1320
weeks = 11
therefore
70(11) + 550 = 1320
Explanation:
70w + 550 = s
let w = weeks
let s = total amount of money in savings
Because every week $70 is added this means 70 multiplied by the weeks gives us the total amount after w(how ever many weeks) weeks. The "+550" comes from the fact that $550 was already in the account therefore after w whatever the amount is there will always be 550 on top.
Total amount of money after
11 weeks: $1320
weeks = 11
therefore
70(11) + 550 = 1320
