A bowling alley charges its customers an hourly rate to bowl plus shoe rental. The hourly rates are per lane. A linear model of this situation contains the values (3,59.25) and (4.77.5), where x represents the number of hours bowled on one
lane, and y represents the total cost for bowling.
What is the rate of change in this linear model?
OA. $4.50 per hour
OB. $54.75 per hour
OC. $18.25 per hour
OD. $9.13 per hour

step-by-step explanation:

good luck

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
