What is the answer and how do you do it

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

He was on the trampoline 29 minutes.

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
