Final answer:
The questions are solved by applying mathematical concepts like unit conversions, proportions, and simple interest calculations. Answers include 27.8 miles per gallon for fuel efficiency, 15 baskets for Cameron's shots, and 18 eighth grade students on the track team, among others.
Step-by-step explanation:
The questions cover several areas of mathematics, including unit conversions, scale models, simple interest, and percentage calculations. Here are the answers to the questions provided:
- Grant's car gets 417 miles / 15 gallons = 27.8 miles per gallon.
- Cameron can make 18 baskets / 2 = 9 baskets out of 30 attempts. If we set up a proportion (9 baskets / 30 attempts = x baskets / 50 attempts), we solve for x to find that Cameron can make 15 baskets in 50 attempts.
- The model of the F/A-18 Hornet uses the scale C. 1 inch = 4 feet.
- 12 cars had an out-of-state license plate (16% of 75).
- There are B. 18 eighth grade students on the track team.
- Mark marked up the ticket by 37.5% (($121 - $88) / $88).
- The loan will accrue $925.50 in interest over two years ($3,425 * 13.5% * 2 years).
- The account will have a total of $972 after 15 years ($800 + $800 * 1.8% * 15 years).
- The financing option that saves $12.75 is D. Option B; saving $12.75.
