A moving company charges a flat rate of \$85 plus and additional \$0.17 per mile driven. How far must the company drive to earn at least \$100? Round to the nearest mile.

a. x ≥ 80

b. x ≥ 84

c. x ≥ 88

d. x ≥ 78

Watermelons cost \$0.35 per pound. Joseph’s watermelon costs between \$4.20 and \$5.25. Which compound inequality correctly represents the possible weights of his watermelon?

a. 12 ≥ x ≥ 15

b. 12 ≤ x ≤  15

c. 8 ≤ x ≥ 12

d. 10 > x > 13

Solve: 41 - 8m = 57

a. 2

b. - 12.25

c. 12.25

d. - 2

Moving: c, because 100 <= 85 + 0.17x, which implies that 15 <= 0.17x which implies that 15/0.17 <= x.

Watermelons: b, because 4.20/0.35 <= x <= 5.25/0.35, which implies that  12 <= x <= 15.

Solve: d, because 41 - 8m = 57 implies that -8m = 57 - 41, which implies that -8m = 16, which implies that

-8m/-8 = 16/-8 which implies that m = -2,
