Select the correct answer.
Mason is getting quotes from two different landscaping companies to put river rock along one side of his house at a depth of 0.5 foot. The
surface area of the space he wishes to install rock in is rectangular and has a length that is eight times its width.
The first company charges $3.50 per cubic foot of rock and $80 for delivery. The second company charges $2.50 per cubic foot of rock and $120
for delivery
Which system of equations can be used to determine the value of the width x at which the cost of the two companies, y, is the same?
.A
y = 282 + 80
y = 2032 + 120
OB. y = 3.5-3 + 80
y = 2,5-3 + 120
OC y = 14:2 + 80
y = 10.12 + 120
OD y = 283 + 80
y = 29,3 + 120
