Using his spending account at the school store, Randy buys pencils which are 12 cents each.  For the first 4 months of school, Randy bought 3, 4, 6, and 9 pencils.  If the function A = .12p represents the amount, A, Randy spent on pencils each month and p is the number of pencils he buys, what is the range of this function?

• {3, 4, 6, 9}

• {0.15, 0.16, 0.18, 0.21}

• {0.36, 0.48, 0.72, 1.08}

• {3.12, 4.12, 6.12, 9.12}

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 te 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?

• 2 ≤ P(t) ≤ 8

• 0 ≤ P(t) ≤ 8

• 10 ≤ P(t) ≤ 17.50

• 0 ≤ P(t) ≤ 17.50
