Question

Alexis opened a savings account with a $120 deposit. Each week she will put $20 into the account. The equation that gives the total amount t in her account is t 120 20w, where w is the number of weeks since she opened the account. How much money will Alexis have in her savings account after 5 weeks?

Answer 1

The amount of money Alexis will have in her savings account after 5 weeks is $ 220.

Explanation:

The equation that gives the total amount t in her account is t=120+20w, where w is the number of weeks since she opened the account.

To calculate the amount of money Alexis will have in her savings account after 5 weeks, you replace the number of weeks w since she opened the account by 5:

t=120+20*5

Solving, you get:

t=120+100

t=220

The amount of money Alexis will have in her savings account after 5 weeks is $ 220.
