• (1) 4.50as

• (2) 4.50(a + s)

• (3) (3.00a)(1.50s)

• (4) 3.00a + 1.50s

The cost of a pack of chewing gum in the vending machine is $0.75. The cost of bottle of juice in the same machine $1.25. Julia has $22.00 to spend on chewing gum and bottles of juice for her team and she must buy seven packs of chewing gum. If b represents the number of bottles of juice, which inequality represents the maximum number of bottles she can buy?

• (1) 0.75b + 1.25(7) ≥ 22

• (2)0.75b + 1.25(7) ≤ 22

• (3) 0.75(7) + 1.25b ≥ 22

• (4) 0.75(7) + 1.25b ≤ 22

A typical cell phone plan has a fixed base fee that includes a certain amount of data and an overage charge for data use beyond the plan. A cell phone plan charges a base fee of $62 and an overage charge of $30 per gigabyte of data that exceed 2 gigabytes. If C represents the cost and g represents the total number of gigabytes of data, which equation could represent this plan when more than 2 gigabytes are used?

• (1) C = 30 + 62(2 - g)

• (2) C = 30 + 62(g - 2)

• (3) C = 62 +30(2 - g)

• (4) C = 62 + 30(g - 2)

What is the solution to 2h + 8 > 3h - 6?
