A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 45% off." If Frank buys two shirts, each with a regular price of $16, how much will he pay for both shirts?
| $7.20 | |
| $8.80 | |
| $24.80 | |
| $17.60 |
By buying two shirts, Frank will save $16 x \( \frac{45}{100} \) = \( \frac{$16 x 45}{100} \) = \( \frac{$720}{100} \) = $7.20 on the second shirt.
So, his total cost will be
$16.00 + ($16.00 - $7.20)
$16.00 + $8.80
$24.80
The total water usage for a city is 45,000 gallons each day. Of that total, 25% is for personal use and 37% is for industrial use. How many more gallons of water each day is consumed for industrial use over personal use?
| 4,900 | |
| 4,050 | |
| 1,400 | |
| 5,400 |
37% of the water consumption is industrial use and 25% is personal use so (37% - 25%) = 12% more water is used for industrial purposes. 45,000 gallons are consumed daily so industry consumes \( \frac{12}{100} \) x 45,000 gallons = 5,400 gallons.
What is the next number in this sequence: 1, 5, 9, 13, 17, __________ ?
| 26 | |
| 21 | |
| 12 | |
| 28 |
The equation for this sequence is:
an = an-1 + 4
where n is the term's order in the sequence, an is the value of the term, and an-1 is the value of the term before an. This makes the next number:
a6 = a5 + 4
a6 = 17 + 4
a6 = 21

A bread recipe calls for 3\(\frac{1}{4}\) cups of flour. If you only have \(\frac{3}{8}\) cup, how much more flour is needed?
| 2 cups | |
| 1\(\frac{5}{8}\) cups | |
| \(\frac{3}{4}\) cups | |
| 2\(\frac{7}{8}\) cups |
The amount of flour you need is (3\(\frac{1}{4}\) - \(\frac{3}{8}\)) cups. Rewrite the quantities so they share a common denominator and subtract:
(\( \frac{26}{8} \) - \( \frac{3}{8} \)) cups
\( \frac{23}{8} \) cups
2\(\frac{7}{8}\) cups
