Frank loaned Betty $1,200 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?
| $1,236 | |
| $1,284 | |
| $1,296 | |
| $1,248 |
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 $1,200
i = 0.08 x $1,200
No payments were made so the total amount due is the original amount + the accumulated interest:
total = $1,200 + $96Solve 2 + (5 + 5) ÷ 2 x 2 - 52

Use PEMDAS (Parentheses, Exponents, Multipy/Divide, Add/Subtract):
2 + (5 + 5) ÷ 2 x 2 - 52
P: 2 + (10) ÷ 2 x 2 - 52
E: 2 + 10 ÷ 2 x 2 - 25
MD: 2 + \( \frac{10}{2} \) x 2 - 25
MD: 2 + \( \frac{20}{2} \) - 25
AS: \( \frac{4}{2} \) + \( \frac{20}{2} \) - 25
AS: \( \frac{24}{2} \) - 25
AS: \( \frac{24 - 50}{2} \)
\( \frac{-26}{2} \)
-13
What is the least common multiple of 8 and 12?
| 93 | |
| 24 | |
| 16 | |
| 92 |
The first few multiples of 8 are [8, 16, 24, 32, 40, 48, 56, 64, 72, 80] and the first few multiples of 12 are [12, 24, 36, 48, 60, 72, 84, 96]. The first few multiples they share are [24, 48, 72, 96] making 24 the smallest multiple 8 and 12 have in common.
A bread recipe calls for 2\(\frac{3}{4}\) cups of flour. If you only have 1\(\frac{1}{8}\) cups, how much more flour is needed?
| 2\(\frac{1}{4}\) cups | |
| 1\(\frac{3}{4}\) cups | |
| 2\(\frac{1}{8}\) cups | |
| 1\(\frac{5}{8}\) cups |
The amount of flour you need is (2\(\frac{3}{4}\) - 1\(\frac{1}{8}\)) cups. Rewrite the quantities so they share a common denominator and subtract:
(\( \frac{22}{8} \) - \( \frac{9}{8} \)) cups
\( \frac{13}{8} \) cups
1\(\frac{5}{8}\) cups
13 members of a bridal party need transported to a wedding reception but there are only 4 3-passenger taxis available to take them. How many will need to find other transportation?
| 2 | |
| 6 | |
| 1 | |
| 9 |
There are 4 3-passenger taxis available so that's 4 x 3 = 12 total seats. There are 13 people needing transportation leaving 13 - 12 = 1 who will have to find other transportation.
