A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 50% off." If Monty buys two shirts, each with a regular price of $40, how much will he pay for both shirts?
| $52.00 | |
| $50.00 | |
| $60.00 | |
| $20.00 |
By buying two shirts, Monty will save $40 x \( \frac{50}{100} \) = \( \frac{$40 x 50}{100} \) = \( \frac{$2000}{100} \) = $20.00 on the second shirt.
So, his total cost will be
$40.00 + ($40.00 - $20.00)
$40.00 + $20.00
$60.00
Which of the following is an improper fraction?
\({2 \over 5} \) |
|
\({7 \over 5} \) |
|
\(1 {2 \over 5} \) |
|
\({a \over 5} \) |
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.
A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 40% off." If Monty buys two shirts, each with a regular price of $11, how much money will he save?
| $2.20 | |
| $4.40 | |
| $1.65 | |
| $1.10 |
By buying two shirts, Monty will save $11 x \( \frac{40}{100} \) = \( \frac{$11 x 40}{100} \) = \( \frac{$440}{100} \) = $4.40 on the second shirt.
A tiger in a zoo has consumed 54 pounds of food in 9 days. If the tiger continues to eat at the same rate, in how many more days will its total food consumtion be 90 pounds?
| 8 | |
| 6 | |
| 15 | |
| 12 |
If the tiger has consumed 54 pounds of food in 9 days that's \( \frac{54}{9} \) = 6 pounds of food per day. The tiger needs to consume 90 - 54 = 36 more pounds of food to reach 90 pounds total. At 6 pounds of food per day that's \( \frac{36}{6} \) = 6 more days.
Which of these numbers is a factor of 72?
| 8 | |
| 33 | |
| 36 | |
