A coach had 10 golf balls for the school's gold team. The coach will give each player on the team 1.5 golf balls. The graph shows the linear relationship between y, the number of golf balls remaining for the team, and x, the number of players on the team. The coach will use no more than 5 players on the school's golf team. Select TWO numbers that would be included in a set that best represents the range of the function for this situation.

• 3

• 2

• 10

• 5.5

• 5

A customer is buying bath towels and hand towels and can spend no more than $80. Each bath towel costs $5, and each hand towel costs $10. The inequality 5x + 10y ≤ 80 represents all possible combinations of x, the number of bath towels, and y, the number of hand towels the customer can buy.

 

Sketch a graph best represents the solution set for this inequality. Remember dashed/solid and shade up/down.
