The math department is selling Pi Day T-shirts. The machine rental is $25. Each shirts cost $7 to make. Write a function rule to model the cost of making shirts, and solve for making 45 shirts.

• f(x) = 25x + 7 f(45) = 1132

• f(x) = 25 + 7x f(45) = 340

• f(x) = 25 + 45x f(7) = 340

• f(x) = 45x + 7 f(25) = 1132
