A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 15% off." If Alex buys two shirts, each with a regular price of $47, how much will he pay for both shirts?
| $7.05 | |
| $86.95 | |
| $56.40 | |
| $39.95 |
By buying two shirts, Alex will save $47 x \( \frac{15}{100} \) = \( \frac{$47 x 15}{100} \) = \( \frac{$705}{100} \) = $7.05 on the second shirt.
So, his total cost will be
$47.00 + ($47.00 - $7.05)
$47.00 + $39.95
$86.95
A tiger in a zoo has consumed 55 pounds of food in 5 days. If the tiger continues to eat at the same rate, in how many more days will its total food consumtion be 99 pounds?
| 9 | |
| 2 | |
| 5 | |
| 4 |
If the tiger has consumed 55 pounds of food in 5 days that's \( \frac{55}{5} \) = 11 pounds of food per day. The tiger needs to consume 99 - 55 = 44 more pounds of food to reach 99 pounds total. At 11 pounds of food per day that's \( \frac{44}{11} \) = 4 more days.
Which of the following is an improper fraction?
\({a \over 5} \) |
|
\(1 {2 \over 5} \) |
|
\({7 \over 5} \) |
|
\({2 \over 5} \) |
A rational number (or fraction) is represented as a ratio between two integers, a and b, and has the form \({a \over b}\) where a is the numerator and b is the denominator. An improper fraction (\({5 \over 3} \)) has a numerator with a greater absolute value than the denominator and can be converted into a mixed number (\(1 {2 \over 3} \)) which has a whole number part and a fractional part.
Damon loaned Ezra $300 at an annual interest rate of 7%. If no payments are made, what is the interest owed on this loan at the end of the first year?
| $27 | |
| $21 | |
| $16 | |
| $26 |
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 = 0.07 x $300
i = $21
If a mayor is elected with 58% of the votes cast and 30% of a town's 9,000 voters cast a vote, how many votes did the mayor receive?
| 2,268 | |
| 1,566 | |
| 1,539 | |
| 1,485 |
If 30% of the town's 9,000 voters cast ballots the number of votes cast is:
(\( \frac{30}{100} \)) x 9,000 = \( \frac{270,000}{100} \) = 2,700
The mayor got 58% of the votes cast which is:
(\( \frac{58}{100} \)) x 2,700 = \( \frac{156,600}{100} \) = 1,566 votes.
