Answer:
$6
Step-by-step explanation:
A=P(1+i.n)
A=200(1+0.01.x 3)
A=206
Thus 206 - 200 = $6
First do the exponents. 20*20=400. 3y is not the same type of number as the rest of them, so move on. (It might help to rearrange the equation: 400-2+3y.)
Subtract 2 from 400. This is 398. The answer is 398+3y.
In the case of multiplication in exponents, if the numbers are the same, their exponents are added.
7 + 8 is written to the power of x, and 3 + 2 is written to the power of y.
12 is 1 more than 11
12 is one less than 13
this ok?
