our club is baking strawberry and apple pies for a bake sale. They need at most 18 pies, and cannot have more than 12 apple pies. Write and graph a system of inequalities to model this system.
A. Let x = the number of strawberry pies. Let y = the number of apples pies
{ x is more than or equal to 0
{ y is more than or equal to 0
{ x + y is more than or equal to 18
{ y is less than or equal to 12
B. { x is more than or equal to 0
{ y is more than or equal to 0
{ x + y is less than or equal to 18
{ y is less than or equal to 12
C. { x is more than or equal to 0
{ y is more than or equal to 0
{ x + y is less than or equal to 18
{ y is more than or equal to 12
D. { x is more than or equal to 0
{ y is more than or equal to 0
{ x + y is more than or equal to 18
{ y is more than or equal to 12
