Last week len spent $18 to bowl 4 games. this week he spent $27 to bowl 6 games. len owns his bowling ball and shoes, so he only has to pay for each game that he bowls. if each of these bowling games cost the same amount of money, what is the constant of proportionality between the money spent and the number of games played?

a. 1.5
b. 2.0
c. 4.5
d. 9.0

C. 4.5

Step-by-step explanation: All you need to do is divide 18 by 4 to find the cost of bowling one game.

18/4 = 4.5

The constant of proportionality between the money spent and the number of games played is C. 4.5.

none.

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
