20x+3
This shouldddd be the answer sorry if I’m wrong, but if you group all the x variables together they add up to twenty, then you just add “+3” being that it has no x and therefore must be put in some form of separate group!
In order to calculate the compound amount and the amount of interest earned, we can use the formula below:

Where A is the compound amount after t years, P is the principal (initial amount) i is the interest rate and n is how many times the interest is compounded in a year.
So, for P = 71000, i = 0.0102, t = 4 and n = 4, we have:

Therefore the compound amount is $73952.87
The amount of interest is:

So the amount of interest earned is $2952.87.
9200/100=92
There are 92 hundreds in 9200.
56 is you answer you need.
