Answer:
Last year the cost was $28.
This year the cost is $36.
$36 - $28 = $8
Percent of increase = amount of increase ÷ original amount
$8/$28 = $0.286
$0.286 · 100 = 28.6%
There has been a 28.6% of change in the cost.

Step-by-step explanation:
(f+g)(x)
f(x)= x-3, g(x)= 2x+8
s=70
t=30
r=32
:D!!
10×7=70
6×5=30
y=6x+16
I hope its right
