Step-by-step explanation:
multiply
when 1 number is given and many is asked means multiply
5.5 × 1.75 = 9.625
price 9.63
The answer is 280 this is your answer
The interest rate would be 20%.
The formula is derived from the compound interest formula

.
We want to isolate r in this equation to rewrite the formula. The first thing we would cancel, outside parentheses, would be p; divide both sides by p and we have

We want to cancel the exponent, t, next. We can raise a power to its reciprocal to undo it; for example, raising a squared amount to the 1/2 power will undo the exponent. We will raise both sides of this to the 1/t power:

Now we cancel the 1 by subtracting, giving us

Using this formula, we plug in 3600 for A, 2500 for p and 2 for t:
