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

75+8(49.99)+4(59.99)

Answer 2

`75+8(49.99)+4(59.99)`

Explanation:

Given that 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.

i.e. membership fee is fixed and once for all payment

So amount she paid for total year would be = membership fee one time+monthly fee of 49.99 for 8 months, 8 times + 59.99 for 4 months , 4 times

=
`75+8(49.99)+4(59.99)\\= 75+400-0.08+200-0.04\\= 675-0.12\\= 674.88`

Thus she has to pay as expression

`75+8(49.99)+4(59.99)`equivalent in value to 674.88
