A farmer has 280 acres of land on which he plans to plant two different crops, crop A and crop B. For each acre of crop A he plants, his expenses are $25, and for each acre of crop B, his expenses are $30. The farmer has a limit of $10,000 for the expenses of planting the 280 acres. If a represents the acres of crop A and b represents the acre of crop B that the farmer plants, which of these represent the limits of a and b?

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?

• $10g+3.5r\le1,500$

• $10g+3.5r\ge1,500$

• $10g+3.5r\le2,500$

• $10g+3.5r\ge2,500$

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 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.
