Question

Jennifer has $50 in her bank account. She deposits $15 per week. Write a linear

equation that finds how much money is in Jennifer's bank account after a certain
number of weeks

Answer 1

y=50+15x

Explanation:

She already has 50 in her bank so you add that to the equation. The 15x is her $15 deposit times (x) weeks.

Answer 2

y=-15x+50

Explanation:

You originally had 50 dollars, so +50. Then, it decreases at a rate of 15 every week, so -15x.

Y is the total number of money she has.

y= -15x+50
