CPM Homework Help : CCA Problem 2-93

Greta is opening a savings account. She starts with $\$100$ and plans to add $\$50$ each week. Write an equation she can use to calculate the amount of money she will have after any number of weeks. How much money will she have after $1$ year?

Hint:

$x$ is the number of weeks starting with week 1, and $y$ is the amount of money.

More Help:

The $y$ -intercept, or $b$ , is the original (starting) price. The slope is the growth rate.
Both of these are given in the problem.
Substitute them into the equation.

There are 52 weeks in a year.
Remember that $x$ is the week number.
