An ice skating rink has two ways you can use the facility. The first option is to pay $20 per visit. The second option is to pay $60 per month, and then only pay $5 per visit. Write and solve an equation to show the number of visits it would take for the cost of the two options to be equal.

Question

A. 20x = 60 + 5x ; x = 4
B. 20x = 60x + 5 ; x = -8
C. 20x = 60 - 5x ; x = 2.4
D. 20x = 60x + 5x ; x = 2.6
E. 20 = 60x + 5 ; x = 0.25
F. 20 + x = 60 + 5 + x ; x = 10

Answer 1

The correct equation is:

20x = 60 + 5x

Solving for x:

20x - 5x = 60
15x = 60
x = 60 / 15
x = 4

Therefore, it would take 4 visits for the cost of the two options to be equal.

The correct answer is:

A. 20x = 60 + 5x ; x = 4
