If a car travels 60 miles in 1 hour, what is the average speed?
| 30 mph | |
| 15 mph | |
| 25 mph | |
| 60 mph |
Average speed in miles per hour is the number of miles traveled divided by the number of hours:
speed = \( \frac{\text{distance}}{\text{time}} \)A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 20% off." If Charlie buys two shirts, each with a regular price of $40, how much money will he save?
| $2.00 | |
| $20.00 | |
| $8.00 | |
| $10.00 |
By buying two shirts, Charlie will save $40 x \( \frac{20}{100} \) = \( \frac{$40 x 20}{100} \) = \( \frac{$800}{100} \) = $8.00 on the second shirt.
Solve 3 + (5 + 2) ÷ 2 x 4 - 42
| \(\frac{5}{6}\) | |
| 1 | |
| \(\frac{3}{5}\) | |
| 1\(\frac{2}{3}\) |
Use PEMDAS (Parentheses, Exponents, Multipy/Divide, Add/Subtract):
3 + (5 + 2) ÷ 2 x 4 - 42
P: 3 + (7) ÷ 2 x 4 - 42
E: 3 + 7 ÷ 2 x 4 - 16
MD: 3 + \( \frac{7}{2} \) x 4 - 16
MD: 3 + \( \frac{28}{2} \) - 16
AS: \( \frac{6}{2} \) + \( \frac{28}{2} \) - 16
AS: \( \frac{34}{2} \) - 16
AS: \( \frac{34 - 32}{2} \)
\( \frac{2}{2} \)

If there were a total of 350 raffle tickets sold and you bought 31 tickets, what's the probability that you'll win the raffle?
| 17% | |
| 16% | |
| 9% | |
| 3% |
You have 31 out of the total of 350 raffle tickets sold so you have a (\( \frac{31}{350} \)) x 100 = \( \frac{31 \times 100}{350} \) = \( \frac{3100}{350} \) = 9% chance to win the raffle.
A bread recipe calls for 2\(\frac{3}{8}\) cups of flour. If you only have 1\(\frac{3}{4}\) cups, how much more flour is needed?
| 2\(\frac{3}{4}\) cups | |
| 1\(\frac{3}{4}\) cups | |
| 2\(\frac{1}{4}\) cups | |
| \(\frac{5}{8}\) cups |
The amount of flour you need is (2\(\frac{3}{8}\) - 1\(\frac{3}{4}\)) cups. Rewrite the quantities so they share a common denominator and subtract:
(\( \frac{19}{8} \) - \( \frac{14}{8} \)) cups
\( \frac{5}{8} \) cups
\(\frac{5}{8}\) cups
