Greetings to everyone.I got 1 math word problem with 2 questions.

Question

.Raymond just got done jumping at Super Bounce Trampoline Center.The total cost of his session was $43,25.
He had to pay a $7 entrance fee and $1,25 for every minute he was on the trampoline.

1.1.write an equation to determine the number of minutes (t) that Raymond was on the trampoline.
1.2.Find the number of minutes he was on the trampoline.

Answer 1

1.1 From the question we see that Raymond will have to pay a $7 entry fee. He will have to pay this amount no matter how long he stays at the center. Thus, the $7 becomes a constant amount in your final equation. Now, for every minute, Raymond must pay an addition $1.25. This implies that for 1 minute in the center Raymond must pay $1.25 for time spent in the center and $7 entry fee. For 2 minutes, Raymond must pay $2.50 (or $1.25 * 2) for time spent in the center plus the $7 entry fee and so forth.

 

Generalizing, Raymond must pay $1.25 *(the number of minutes spent at the center) plus the $7 entry fee. If we let (t) represent the number of minutes Raymond spent at the center and (C) represent the cost to Raymond, then an equation describing the cost to Raymond is given by the following: 

C = $7 + $1.25(t)

 

For this specific question, we know that Raymond's cost was $43.25. So substituting $43.25 for C in the above equation, we get,

$43.25 = $7 + $1.25(t) <-Answer

 

1.2 To find the number of minutes Raymond was on the trampoline, you must solve the answer from (1.1) for t.
