Question

Keecia joins a gym. She pays a membership fee of $75.00 and $49.99 per month for the first 8 months. The gym increases its rates, and she must pay $59.99 per month for the next 4 months. Which numerical expression can be used to find the total cost of the first year of Keecia’s gym membership?

Answer 1

$165 is the total cost of the first year of Keecia’s gym membership

Explanation:

formula for direct proportion : y = kx

x = 50

y = 75

50 = k * 75

k = 75/50

k = 3/2x

substitute y = 60

60 = 3/2x

x = 3/2 * 60

x = 90

$90 + $75 = $165
