• Q2
Veronica is ordering trophies for her school. Company P charges \$3.50 for each trophy and a one-time engraving fee of \$25. Company R charges \$7.50 for each trophy and a one-time engraving fee of \$17. Which inequality can be used to find x, the minimum number of trophies that can be ordered so that the total charge at Company P is less than the total charge at Company R?
3.5 + 25x < 7.5 + 17x
3.5x + 25 > 7.5x + 17
3.5 + 25x > 7.5 + 17x
3.5x + 25 < 7.5x + 17

• Q3
Two eighth-grade classes are selling raffle tickets to raise money. • One class is selling tickets for \$2.50 each and has already raised \$350. • The other class is selling tickets for \$3.00 each and has already raised \$225. Which equation can be used to find t, the number of tickets each class needs to sell so that the total amount raised is the same for both classes?
350t + 2.50 = 225t + 3
2.50 t + 350 = 3t + 225
3t + 350 = 2.50 t + 225
