C= $60.00+$0.05d is the linear equation, if you have any questions feel free to ask. (:
A=45
A=kx/y
where k is constant
substituting the values for k
k= 20×9/6=30
when x=9, y=6
A= 30×9/6=45
The percent of the increase is

I is the increasing value
N is the new value
O is the original value
The price of the cooler is $28.50, then
O = 28.50
The selling price of the cooler is $40.76, then
N = 40.76
We will substitute them in the rule above to find I

Let us calculate it
I = 43.0175 %
Round it to the nearest percent
I = 43%
The answer is D
