Question

Last week Len spent $18 to bow 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 ach game thar he towis. If each of these bowling games costs the same amount of money, what is the constant of propertionality between the money spent and the number of games played?

Answer 1

Answer: $4.50

Explanation:

Based on the question, we are going to solve this using direct proportion. The formula will be:

y = kx

where,

y = Money spent = $18

x = number of games played = 4

k = constant of proportionality

Note that we can use either the amount spent last week or the amount spent this week since the bowling games costs the same amount of money.

Since y = kx

18 = 4k

k = 18/4

k = $4.50

The constant of proportionality is 4.50
