Question

At Santorini's Shakes, a regular milkshake costs $3.50. A larger milkshake can be purchased for an additional $0.40 per ounce above the regular size.

If x represents the number of ounces above the regular size, which inequality shows how much can be added to the regular size for a milkshake that costs under $5.00?

Answer 1

5=0.40x+3.50

He can get 3 extra ounces

Explanation:

5.00-3.50=1.50 so an extra $1.50 to spend on extra ounces

1.50/0.40=3

0.40(3)+3.50= $4.70

So the most ounces he can get is 3

He will have $0.30 left
