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?

Step-by-step 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

=

Thus she has to pay as expression

equivalent in value to 674.88

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
