Answer:
y=-15x+50
Step-by-step 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
Answer:
y=50+15x
Step-by-step explanation:
She already has 50 in her bank so you add that to the equation. The 15x is her $15 deposit times (x) weeks.
