Sophia had $50 she put into a savings account. if she say she $15 per week for one year, how much will she have saved altogether?

Well first we need think about how many years are in a week. Do you know how many weeks are in a year?

The first step would be to write an equation for this.

We'll make w = weeks and M = total money.

M = 15w + 50

There are 52 weeks in a year so plug 52 in for w.

M = 15(52) + 50
M = 830

She would have $830 after one year.
