Diane scored 88% on the test meaning she earned 88% of the possible points on the test. There were 120 possible points on the test so she earned 120 x 0.88 = 105 points. Each question is worth 3 points so she got \( \frac{105}{3} \) = 35 questions right.
Bob loaned Roger $1,100 at an annual interest rate of 9%. If no payments are made, what is the interest owed on this loan at the end of the first year?
| $24 | |
| $6 | |
| $20 | |
| $99 |
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 $1,100
i = 0.09 x $1,100
i = $99
How many 2 gallon cans worth of fuel would you need to pour into an empty 20 gallon tank to fill it exactly halfway?
| 2 | |
| 9 | |
| 10 | |
| 5 |
To fill a 20 gallon tank exactly halfway you'll need 10 gallons of fuel. Each fuel can holds 2 gallons so:
cans = \( \frac{10 \text{ gallons}}{2 \text{ gallons}} \) = 5
In a class of 31 students, 15 are taking German and 10 are taking Spanish. Of the students studying German or Spanish, 7 are taking both courses. How many students are not enrolled in either course?
| 21 | |
| 16 | |
| 13 | |
| 10 |
The number of students taking German or Spanish is 15 + 10 = 25. Of that group of 25, 7 are taking both languages so they've been counted twice (once in the German group and once in the Spanish group). Subtracting them out leaves 25 - 7 = 18 who are taking at least one language. 31 - 18 = 13 students who are not taking either language.

There are 3 5-passenger taxis available so that's 3 x 5 = 15 total seats. There are 19 people needing transportation leaving 19 - 15 = 4 who will have to find other transportation.
