The answer is the forth one.
Answer:
<u>7 groups of 8 = 6 groups of 8 plus 1 group of 8</u>
Step-by-step explanation:
1. Let's review the information given to answer the question correctly:
7 groups of 8 = 6 groups of 8 plus ?
2. Let's answer the question, this way:
How much are 7 groups of 8? 56 = 7 * 8
How much are 6 groups of 8? 48 = 6 * 8
What is the difference between 7 groups of 8 and 6 groups of 8?
(7 - 6 ) * 8 = 1 * 8
Therefore,
<u>7 groups of 8 = 6 groups of 8 plus 1 group of 8</u>
Answer:
$18.15
Explanation:
In this case, we can add the percentages because they are taken of the same number.
The state sales tax, 4.6%, will be taken of $220, the purchase price. The county sales tax, 3.65%, will also be taken of $220, the purchase price. Since they are being taken of the same number, we can add the percentages:
4.6+3.65 = 8.25%
Now we can take 8.25% of 220:
8.25% = 8.25/100 = 0.0825
0.0825(220) = $18.15
Answer:
$798
Step-by-step explanation:
Jack invested $7100 compounded continuously at an interest rate of 3⅝% which is 0.03625
Formula for future value of continuous compounding is;
FV = PVe^(rt)
Where;
FV is future value
PV is present value
r is interest rate
t is time
After 19 years;
FV = 7100 × e^(0.03625 × 19)
FV = $14137.697
Henry invested $7100 compounded monthly at an interest rate of 3⅜% which is 0.03375.
Formula for FV of monthly compounding is;
FV = PV(1 + i)^(n)
FV = 7100(1 + 0.03375)^(19)
FV = $13339.922
Thus, amount Jack has more than Henry = 14137.697 - 13339.922 = $797.775
Approximating to the nearest dollar gives $798
