A bread recipe calls for 3\(\frac{3}{8}\) cups of flour. If you only have \(\frac{3}{8}\) cup, how much more flour is needed?
| 1\(\frac{1}{2}\) cups | |
| 1 cups | |
| 3 cups | |
| 2 cups |
The amount of flour you need is (3\(\frac{3}{8}\) - \(\frac{3}{8}\)) cups. Rewrite the quantities so they share a common denominator and subtract:
(\( \frac{27}{8} \) - \( \frac{3}{8} \)) cups
\( \frac{24}{8} \) cups
3 cups
A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 20% off." If Damon buys two shirts, each with a regular price of $43, how much will he pay for both shirts?
| $77.40 | |
| $34.40 | |
| $62.35 | |
| $51.60 |
By buying two shirts, Damon will save $43 x \( \frac{20}{100} \) = \( \frac{$43 x 20}{100} \) = \( \frac{$860}{100} \) = $8.60 on the second shirt.
So, his total cost will be
$43.00 + ($43.00 - $8.60)
$43.00 + $34.40
$77.40
How many 9-passenger vans will it take to drive all 95 members of the football team to an away game?
| 13 vans | |
| 8 vans | |
| 11 vans | |
| 7 vans |
Calculate the number of vans needed by dividing the number of people that need transported by the capacity of one van:
vans = \( \frac{95}{9} \) = 10\(\frac{5}{9}\)
So, it will take 10 full vans and one partially full van to transport the entire team making a total of 11 vans.
Convert y-5 to remove the negative exponent.
| \( \frac{-1}{-5y} \) | |
| \( \frac{1}{y^5} \) | |
| \( \frac{-1}{y^{-5}} \) | |
| \( \frac{5}{y} \) |
To convert a negative exponent to a positive exponent, calculate the positive exponent then take the reciprocal.
Roger loaned Alex $300 at an annual interest rate of 2%. If no payments are made, what is the interest owed on this loan at the end of the first year?
| $48 | |
| $15 | |
| $2 | |
| $6 |
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 $300
i = 0.02 x $300
i = $6
