The cost for renting a weed trimmer varies directly with the number of hours used. A weed trimmer rented for 5 hours costs $32.5
0.Which choice shows the direct variation equation and the amount of rent for 8 hours in this situation? A y = $6.5x, y = $52.00
B y = $32.5x, y = $260.00
C y = $5x, y = $40.00
D y = $8x, y = $64.00
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:'
