Answer:
1. The first problem is wrong, it should be 0.5(3(15) + 2(20)) because the parentheses make sure that every purchased item is being divided by 2 (multiplying by 0.5 is the same as dividing by 2)
2. The second problem is partially correct. The first two answers you have checked are correct, but the last one is wrong. The third answer should be 6 + 12 instead because that's just a simplified version of 2(3) + 6(2), meaning they are equal
3. I cannot read your answers in the "Why or Why Not" column in the third problem, but the answers you gave in the "Evaluate" and "Does It Work?" columns are all correct.
Given:
• Amount to save, A = $28,000
,
• Time, t = 6 years
,
• Interest rate, r = 5.3% ==> 0.053
,
• Number of times compounded = quarterly = 4 times
Let's find the amount that must be deposited into the account quarterly.
Apply the formula:
Where:
FV is the future value = $28,000
r = 0.053
n = 4
t = 6 years
Thus, we have:
Let's solve for P.
We have:
Solving further:
Divide both sides by 28.0384237:
Therefore, the amount that must be deposited quarterly into the account is $998.60
