When : 36 ÷ n = 4
10) n = 9
Plug in 9 for n
36 ÷ 9 = 4
Correct / true
11) n = 6
Plug in 6 for n
36 ÷ 6 = 4
Incorrect / false
12) n = 5
Plug in 5 for n.
36 ÷ 5 = 4
Incorrect / false
~Hope I helped!~
The answer would have to be 4
Answer:
4)P = $615.38. 5)P = $1,482.35
Step-by-step explanation:
<u>4)P = $615.38</u>
Equation:
P = A / (1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year.
Solving our equation:
P = 640 / ( 1 + (0.04 × 1)) = 615.38461538462
P = $615.38
The principal investment required to get a total amount, principal plus interest, of $640.00 from simple interest at a rate of 4% per year for 1 years is $615.38.
<u>2)P = $1,482.35</u>
Equation:
P = A / (1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 12%/100 = 0.12 per year.
Solving our equation:
P = 2016 / ( 1 + (0.12 × 3)) = 1482.3529411765
P = $1,482.35
The principal investment required to get a total amount, principal plus interest, of $2,016.00 from simple interest at a rate of 12% per year for 3 years is $1,482.35.
