The total cost (TC) of the gym membership is composed of:

1. the amount of the initial membership fee that is paid once, right at the beginning of membership. You don't say what that amount is, so I'll call it O for one-time payment.

2. the monthly fee paid each month during the membership. I'll call that F.

3. the number of months that a person is a member. I'll call that M.

TC = O + (F x M)

For example, suppose the one-time initial membership fee is $70, the monthly fee is $30, and you've been a member for 6 months:

TC = $70 + ($30 x 6)

TC = $70 + $180

TC = $250

For your example, just plug your numbers in the equation. The only number you don't know is the one-time initial fee, so that is what you are solving for:

$250 = O + ($35 x 6)

$250 = O + $210

$40 = O

nicely, all of us comprehend that the hypotenuse is 10, so: 10^2 = a^2 + b^2 And if a is the area from the floor to the suitable of the ladder, then a - 2 is the area from the bottom of the ladder to the wall, so: one hundred = (a - 2)^2 + a^2 one hundred = a^2 - 4a + 4 + a^2 a^2 - 2a - 40 8 = 0 (a - 8)(a + 6) = 0 a = 8, meaning the area from the floor to the suitable of the ladder is 8 feet, and the area from the bottom of the ladder to the construction is six feet. solid success, insha'Allah. :)
