Natasha and her friends go out for ice cream. They decide to create their own ice cream, which costs $1.60 plus 8 cents per topping. If x represents the number of toppings on the ice cream, then which equation describes y, the total cost for the ice cream?

• y = (.08 + 1.60)x

• y = .08 + 1.60x

• y = 1.60 + .08x

• y = 8x + 1.60

• y = 2x + 3

• y = –2x + 3

• y = 1/2 x + 3

• y = –1/2 x + 3

• A. x = 3, slope is 0.

• B. y = 3, slope is 0.

• C. x = 3, slope is undefined.

• D. y = 3, slope is undefined.

A pizza shop needs at least 600 lbs of cheese per month. The storage freezer contains 23 lbs of cheese on the first day of the month. If cheese is bought in 50 lb bags, which inequality can be used to calculate how many bags of cheese, x, are needed for the month?

• 23 + 50x ≥ 600

• 23 + 50x > 600

• 23 + 50x < 600

• 23 + 50x ≤ 600
