So we know the gym charges $10 to join, and the $4 every visit. He wants to visit 20 times, so we multiply 20 by 4 to get the price of 20 visits, which is $80. Then we add $10 for the joining fee. The total will cost him $90. That means he needs to save $44 to visit 20 times. Hope that helps!

Theorems are statements that have already been proven, and are used to prove other statements.
A postulate is a statement that is assumed to be true, and is used to prove other statements.
A corollary is a direct consequence of a proven fact, and as such, are used to prove other statements.
A definition is an absolute truth, so it can also be used to prove another statement.
