Question 33769
1. Write a formula that describes the function for: A large pizza costs $12.00 plus 30 cents for each topping. Express the total cost C as a function of the number of toppings t.
C = .3t + 12 is the function
or, you can graph this as y = (3/10)x + 12
-------------------------------------------------------------------------------
2. Graph 5y - 3x >= 25
5y >= 3x + 25
y >= (3/5)x + 5
graph y = (3/5)x + 5 as a solid line .... then, shade above the solid line
