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
