A triathlon course includes a 100m swim, a 20.1km bike ride, and a 11.6km run. What is the total length of the race course?
| 31.1km | |
| 63.8km | |
| 59.5km | |
| 31.8km |
To add these distances, they must share the same unit so first you need to first convert the swim distance from meters (m) to kilometers (km) before adding it to the bike and run distances which are already in km. To convert 100 meters to kilometers, divide the distance by 1000 to get 0.1km then add the remaining distances:
total distance = swim + bike + run
total distance = 0.1km + 20.1km + 11.6km
total distance = 31.8km

A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 40% off." If Alex buys two shirts, each with a regular price of $30, how much money will he save?
| $7.50 | |
| 66 | |
| 94 | |
| $12.00 |
By buying two shirts, Alex will save $30 x \( \frac{40}{100} \) = \( \frac{$30 x 40}{100} \) = \( \frac{$1200}{100} \) = $12.00 on the second shirt.
9 members of a bridal party need transported to a wedding reception but there are only 2 3-passenger taxis available to take them. How many will need to find other transportation?
| 9 | |
| 8 | |
| 3 | |
| 2 |
There are 2 3-passenger taxis available so that's 2 x 3 = 6 total seats. There are 9 people needing transportation leaving 9 - 6 = 3 who will have to find other transportation.
A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 15% off." If Monty buys two shirts, each with a regular price of $19, how much will he pay for both shirts?
| $25.65 | |
| $2.85 | |
| $35.15 | |
| $20.90 |
By buying two shirts, Monty will save $19 x \( \frac{15}{100} \) = \( \frac{$19 x 15}{100} \) = \( \frac{$285}{100} \) = $2.85 on the second shirt.
So, his total cost will be
$19.00 + ($19.00 - $2.85)
$19.00 + $16.15
$35.15
