12 b. Marisol has the highest score in English.
I acidently removed the stuff but anyways the answer is 12:27 or 12 to 27
do 12 + 15 = 27, and so 12 to 27 :)
Let the cost for renting be y and the number of hours be x
then:
y=kx
where:
k is the constant of proportionality
k=y/x
y=$32.5 when x=5 hours
thus;
k=32.5/5
k=6.5
hence the equation is:
y=6.5x
thus the value of y when x=8 hours will be:
y=6.5(8)=$52
Answer:'
<span>A y = $6.5x, y = $52.00</span>
