Roger loaned April $1,000 at an annual interest rate of 8%. If no payments are made, what is the total amount owed at the end of the first year?

71% Answer Correctly
$1,060
$1,080
$1,090
$1,010

Solution

The yearly interest charged on this loan is the annual interest rate multiplied by the amount borrowed:

interest = annual interest rate x loan amount

i = (\( \frac{6}{100} \)) x $1,000
i = 0.08 x $1,000

No payments were made so the total amount due is the original amount + the accumulated interest:

total = $1,000 + $80
total = $1,080

Find the average of the following numbers: 19, 11, 16, 14.

75% Answer Correctly
13
16
15
12

Solution

To find the average of these 4 numbers add them together then divide by 4:

\( \frac{19 + 11 + 16 + 14}{4} \) = \( \frac{60}{4} \) = 15


3

A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 20% off." If Alex buys two shirts, each with a regular price of $48, how much will he pay for both shirts?

57% Answer Correctly
$57.60
$67.20
$9.60
$86.40

Solution

By buying two shirts, Alex will save $48 x \( \frac{20}{100} \) = \( \frac{$48 x 20}{100} \) = \( \frac{$960}{100} \) = $9.60 on the second shirt.

So, his total cost will be
$48.00 + ($48.00 - $9.60)
$48.00 + $38.40
$86.40

What is 7c5 x 9c3?

75% Answer Correctly
16c3
63c3
63c8
16c5

Solution

To multiply terms with exponents, the base of both exponents must be the same. In this case they are so multiply the coefficients and add the exponents:

7c5 x 9c3
(7 x 9)c(5 + 3)
63c8


5

What is \( 3 \)\( \sqrt{8} \) + \( 7 \)\( \sqrt{2} \)

35% Answer Correctly
21\( \sqrt{16} \)
13\( \sqrt{2} \)
10\( \sqrt{16} \)
10\( \sqrt{2} \)

Solution

To add these radicals together their radicands must be the same:

3\( \sqrt{8} \) + 7\( \sqrt{2} \)
3\( \sqrt{4 \times 2} \) + 7\( \sqrt{2} \)
3\( \sqrt{2^2 \times 2} \) + 7\( \sqrt{2} \)
(3)(2)\( \sqrt{2} \) + 7\( \sqrt{2} \)
6\( \sqrt{2} \) + 7\( \sqrt{2} \)

Now that the radicands are identical, you can add them together:

6\( \sqrt{2} \) + 7\( \sqrt{2} \)
(6 + 7)\( \sqrt{2} \)
13\( \sqrt{2} \)
