Question

What is the answer and how do you do it

Answer 1

Answer:

29 minutes

Step-by-step explanation:

Cost of trampoline = fixed entrance fee + cost per minute

The fixed entrance fee is $7.

The cost per minute is $1.25

Let t be the number of minutes he is on the trampoline.

For 1 minute, he pays $1.25 * 1.

For 2 minutes, he pays $1.25 * 2.

For t minutes, he pays $1.25 * t.

The cost for t minutes is 1.25t.

The total cost is the fixed cost plus the cost per minute.

Total cost = 7 + 1.25t

He was on the trampoline and paid $43.25. His total cost was $43.25.

That means that 7 + 1.25t = 43.25.

The equation is

7 + 1.25t = 43.25

Now we solve the equation for t.

Subtract 7 from both sides.

1.25t = 36.25

Divide both sides by 1.25

t = 29

Answer: He was on the trampoline 29 minutes.
