John has $200 in his savings account. He deposits $50 each week. What is the rate of change? I really need help fast!

25% increase each week

Step-by-step explanation:

200 divided by 50 = 4

50 + 50 + 50 + 50 = 200 (there is four)

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
