Jennifer scored 98% on her final exam. If each question was worth 4 points and there were 360 possible points on the exam, how many questions did Jennifer answer correctly?
| 97 | |
| 96 | |
| 81 | |
| 88 |
Jennifer scored 98% on the test meaning she earned 98% of the possible points on the test. There were 360 possible points on the test so she earned 360 x 0.98 = 352 points. Each question is worth 4 points so she got \( \frac{352}{4} \) = 88 questions right.
How many 15-passenger vans will it take to drive all 52 members of the football team to an away game?
| 4 vans | |
| 10 vans | |
| 8 vans | |
| 6 vans |
Calculate the number of vans needed by dividing the number of people that need transported by the capacity of one van:
vans = \( \frac{52}{15} \) = 3\(\frac{7}{15}\)
So, it will take 3 full vans and one partially full van to transport the entire team making a total of 4 vans.
\({b + c \over a} = {b \over a} + {c \over a}\) defines which of the following?

commutative property for multiplication |

distributive property for multiplication |

commutative property for division |
The distributive property for division helps in solving expressions like \({b + c \over a}\). It specifies that the result of dividing a fraction with multiple terms in the numerator and one term in the denominator can be obtained by dividing each term individually and then totaling the results: \({b + c \over a} = {b \over a} + {c \over a}\). For example, \({a^3 + 6a^2 \over a^2} = {a^3 \over a^2} + {6a^2 \over a^2} = a + 6\).
Bob loaned Monica $300 at an annual interest rate of 7%. If no payments are made, what is the total amount owed at the end of the first year?
| $309 | |
| $324 | |
| $303 | |
| $321 |
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
No payments were made so the total amount due is the original amount + the accumulated interest:
total = $300 + $21
