Answer:
A.) $56
Step-by-step explanation:
1. Convert 7% into the numerical version by either
A. Moving the decimal two spaces to the right, giving us .07
or
B. Making 7% into a fraction, 7/100
2. Now make an equation with the total amount of money (M) multiplied by the interest (P) inside of parenthesis. This will give us 7% of $800 in your case.
(800 × .07) → 56
3. Then, multiply by the number of years the interest has been accumulated.
56 × 1
The official equation for this is: a = p(1 + r)^t
a = amount at end (initial amount + interest gained)
p = initial amount
r = rate (percent interest)
t = time in years

Answer:173/10
Step-by-step explanation:
10^6 = 10 *10*10*10*10*10 = 1,000,000
