x≥3
y>3
A set of weights includes a 45 lb barbell and 6 pairs of weight plate. Each pair of plates weighs 20 lb. If x pairs of plate are added to the barbell, the total weight of the barbell and plates in pounds can be represented by f(x)=20x+45.
What is the range of the function in this situation?
{0, 1, 2, 3, 4, 5, 6,}
{45, 65, 85, 105, 125, 145, 165}
{0, 2, 4, 6}
{45, 55, 65, 75,85,95}
The total cost in dollars to buy uniforms for the players on a volleyball team can be found using the function c(u) = 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 the volleyball team, what is the domain of the function for this situation?
0<u<12
0<c≤425.65

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?
{10, 11.25, 12.50, 13.75, 15, 16.25, 17.50}
{2, 3, 4, 5, 6, 7, 8}
10 ≤ P(t) ≤ 17.50
0 ≤ P(t) ≤ 17.50
