The cost of a cheese pizza is $9.99 plus $0.35 for each additional topping, t. a) write an inequality that can be used to represent the cost of a pizza that is at most $12. b) what is the most number of toppings that a pizza can have and still be at most $12?

a) is $10.34

b) is 6 toppings

a) at most means it can cost $12 or less

so the inequality sign would be ≤

you would then need to multiply the number of toppings by the 0.35 for each one and add it to the cost of the cheese pizza.

the equation would be 9.99 + 0.35x ≤ 12

b) using the above equation:

9.99 + 0.35x ≤ 12

subtract 9.99 from each side:

0.35x ≤2.01

divide both sides by 0.35:

x ≤ 2.01 / 0.35

x ≤5.74

at most you could have 5 toppings.

the 5 topping pizza would cost: 0.35 x 5 = 1.75 + 9.99 = $11.74
