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:
x = 4
Step-by-step explanation:
given f(x) = 11 then equate f(x) = 11 and solve for x
4x - 5 = 11 ( add 5 to both sides )
4x = 16 ( divide both sides by 4 )
x = 4 ← value of x in the domain
