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

• 0.75b + 1.25(7) ≥ 22

• 0.75b + 1.25(7) ≤ 22

• 0.75(7) + 1.25b ≥ 22

• 0.75(7) + 1.25b ≤ 22

Connor wants to attend a town carnival. The price of admission to the carnival is $4.50, and each ride costs an additional 79 cents. If he can spend at most $16.00 at the carnival, which inequality can be used to solve for r, the number of rides Connor can go on, and what is the maximum number of rides he can go on?

• 0.79 + 4.50r ≤ 16.00 ; 3 rides

• 0.79 + 4.50r ≤ 16.00 ; 4 rides

• 4.50 + 0.79r ≤ 16.00 ; 14 rides

• 4.50 + 0.79r ≤ 16.00 ; 15 rides
