The student council is selling rolls of gift wrap and ribbon for the holiday season. The council charges $10 for a roll of gift wrap and $3.50 for a roll of ribbon. The student council has a fundraising goal of at least $1,500. Let g equal the number of rolls of gift wrap sold and let r equal the number of rolls of ribbon sold. Which inequality represents the student council meeting its fundraising goal?

The solutions to the equation f(x) = g(x) are -2 and 1. If f and g are graphed on the same coordinate plane, which statement must be true?

• The functions will intersect at x = -2 and x = 1.

• The functions will intersect at y = -2 and y = 1.

• Both functions will have y--intercepts at -2 and 1.

• Both functions will have x--intercepts at -2 and 1.
