First, multiply the numbers in the <span>parentheses, which is </span>3 times 7 is 21.
Then divide 40 by 1. 40/1 = 40
40 plus 3 is 43, 43 minus 21 is 22.
PLus 7 minus 5 is 24.

First things first. Think of the word
PEMDAS meaning parenthesis, exponents, multiplication, division, addition, subtraction.
First you would check for parenthesis which you do (3x7) so multiply both which come out to 21.
We can skip exponents and multiplication since we have already done it or may not have it. Next is division. Multiply 40 divide by 1 which is 40 now add 3 so 43. And lastly subtract 7-5=2
Your new equation is 43-21+2. So your answer comes out to 24! Hoped this helped.

<h3>What is compound interest?</h3>

Compound interest is the amount charged on the principal amount and the accumulated interest with a fixed rate of interest for a time period.

The formula for the final amount with the compound interest formula can be given as,

A=P\left(1+\dfrac{R}{n\times100}\right)^{nt}

Here, A is the final amount (principal plus interest amount) on the principal amount P of with the rate r of in the time period of t.

Viola took out a $8,470 Stafford loan at the beginning of her four-year college career. The loan has a duration of ten years and an interest rate of 7. 5%, compounded monthly.

Put this values in the above formula as,

A=8470\left(1+\dfrac{7.5}{12\times100}\right)^{12\times4}\\A=11422.6348

For the four years, the monthly payment is,

m=\dfrac{11422.6348}{12\times4}\\m=237.97

The monthly payment of unsubsidized loan is $237.97.

The monthly payment of subsidized loan is $202.80.

The difference between the unsubsidized and subsidized loan monthly payment is,

d=237.97-202.80\\d=35.17\\d\approx 35.05

Thus, the Viola’s monthly payment more than the loan is unsubsidized than if the loan is subsidized is $35.05.
