Annually cumulating interest can be determined by the following formula:

r represents the interest rate as a decimal, and P represents the starting amount of money.
a)
y=4 x +(1.6 X 10)
b)
y=4x +16
c)
x=0 y=0+16 (0,16)
x=1 y=4 +16 (1,20) first day it cost $20
x=2 y=8+16 (2,24) second day it cost $24
x=3 y=12+16 (3, 28) third day it cost $28
plot (0,16) , (1,20), (2,24), (3, 28)
i hope this help
I think its not a correct solution of given equations.
