a=p(1+r)^t
a=final number
p=principal balance (initial)**without interest**
r=interest rate
t=the amount of time
p=$4000
t= 7yrs
r=2%=0.02
we need to turn 2% into a decimal, to do that you divide 2 by 100 which is 0.02
now we rewrite the equation-
a=4000(1+0.02)^7
a=4000*1.1486
If a decimal number, x = 0.3 then 10x is 10 multiplying 0.3 the result is 3
<h3>What is a decimal ?</h3>
A decimal is a number that is divided into two parts: a whole and a fraction.
Between integers and fractions, decimal numbers reflect the numerical value of whole
<h3>How to find 10x</h3>
0.3 is x which is a decimal
10 multiplies 0.3 the result is 3
The process involve converting a fraction to a whole number as the result of multiplication changed the number system from decimal to a whole number

The total payment = y
The number of copies to be sold = x
In part (a):
Change of pay = discrepancies between (x+1) sale and (x) sale of copies for every copy sold
In part (b)
