The total cost in dollars to buy uniforms for the players on the volleyball team can be found using the function c = 34.95u + 6.25, where u is the number of uniforms bought.  If there are at least 8 players but not more than 12 players on team, what is the domain of the situation?

HINT: make a table!

• 0 < u ≤ 12

• 0 < c ≤ 425.65

• {8, 9, 10, 11, 12}

• {295.85, 320.80, 355.75, 390.70, 425.65}

The student council set its members on four field trips during the school year.  The number of buses needed to transport the members on each trip is a function of the number of members who went on the trip.  This function consists of only the ordered pairs (52, 3), (72, 4), (86, 5), and (105, 6).  What is the domain for this situation?

• {52, 105}
• {3, 4, 5, 6}
• {52, 72, 86, 105}
• {3, 4, 5, 52, 72, 86, 105}

A pizza shop sells pizza for $7.50 each plus $1.25 per topping.  The total price of the pizzas can be determined by the function P(t) = 7.5 + 1.25t, where t is the number of toppings orders and P(t) is the total price of the pizza.  The shop has a delivery policy that all orders must have a minimum of 2 toppings and maximum of 8 toppings for a delivery.  Which inequality represents the range of the situation?

HINT: make a table!

• 2 ≤ P(t) ≤ 8

• 0 ≤ P(t) ≤ 8

• 10 ≤ P(t) ≤ 17.50

• 0 ≤ P(t) ≤ 17.50
