Question

Mr. Krabs has decided to add pizza to the Krusty Krab menu in addition to Krabby Patties. A Krusty Krab Pizza requires 8 cups of seaweed and 1 cup of the Secret Formula. A Krabby Patty requires 1 cup of seaweed and 1 cup of the Secret Formula. The Krusty Krab has at most 40 cups of seaweed and 12 cups of secret formula available. Mr. Krabs makes a profit of $3 for each Krusty Krab Pizza and $1 for each Krabby Patty.
X = the number of Krusty Krab Pizzas
Y = the number of Krabby Patties
P = profit

Which constraint does not represent the information in the above problem?
A) x ≥ 0
B) 8x + 1y ≤ 40
C) y ≥ 0
D) 1x + 1y ≥ 12

Answer 1

D

The secret formula constraint should be x + y ≤ 12 (at most 12 cups), not x + y ≥ 12.
