Lena has a gift card to use to buy music albums. Each album costs $12.50. The function

g(x) = -12.50x + 100

represents the remaining value of the gift card, in dollars, after purchasing x albums.

Based on the function, determine all the true statements:

• g(0) = 100 represents the original value of the gift card.

• g(5) = 37.50 represents the remaining value, in dollars, of the gift card after Lena purchased 5 albums.

• g(7) = 12.50 represents the remaining value, in dollars, of the gift card after Lena purchased 7 albums.

• g(3) = 62.50 represents the remaining value, in dollars, of the gift card after Lena purchased 3 albums.

• g(10) = 0 represents the remaining value of the gift card after Lena purchased 10 albums.

Lena is looking to purchase a used boat. She is choosing between two boats. Boat X costs $3200, gets 20 mpg, and has estimated repairs of $500. Boat Y costs $2800, gets 22 mpg, and has estimated repairs of $400. Lena estimates she will drive the boat at least 50 miles per month. The average cost of gasoline per gallon in her city is $3.95. Lena plans on owning the boat for 4 years.

Which boat will cost Lena the least to buy and use? How much will the difference in cost be?

• Boat X will cost less for Lena. The difference in cost will be $543.20.

• Boat Y will cost less for Lena. The difference in cost will be $543.20.

• Boat X will cost less for Lena. The difference in cost will be $800.

• Boat Y will cost less for Lena. The difference in cost will be $800.

The table below lists the total cost in dollars C for parking h hours on a street in Downtown Orlando. Write an equation that can be used to determine C, the total cost in dollars, a customer will be charged for parking h hours.

• C = 2.00h + 1.50

• C = 2.25h + 1.50

• C = 2.00h + 2.00

• C = 3.00h + 2.50

A student bought 4 pencils and 6 erasers. The price of each eraser is $3 more than the price of each pencil. If the student spent a total of $42 on pencils and erasers, which linear equation can be used to find p , the price of each pencil in dollars?

• 4p + 6(p + 3) = 42

• 6p + 4(p + 3) = 42

• 4p + 6(p - 3) = 42

• 6p + 4(3 - p) = 42
