Question

Jesse opened a savings account with a deposit of $70. He deposited an additional $10 each week. Part A: Write and solve an equation that can be used to determine the number of weeks Jesse has to make deposits for the money in the account to equal $200

Answer 1

200-70= x

x/10=W

Explanation:

$200 is the amount he wants save.

He already saved $70. (subtracting 70 from 200 gives me 130)

130 is what he still needs so if i divide that by 10 ( the amount hes putting in each week). this leaves me with 13. 13 is the amount of weeks left until he reaches his goal.
