Myranda received a movie gift card for $100 to her

PSYCHO15rus [73]

Answer:

The graph in the attached figure

Step-by-step explanation:

Let

x ---> represents the number of matinee tickets she could purchase

y ---> represents the number of evening tickets she could purchase

we know that

The number of matinee tickets (x) multiplied by $7.50 each plus the number of evening tickets (y) multiplied by $12.50 each must be at most (less than or equal to) $100

The inequality that represent this problem is

$7.50x+12.50y\leq 100$

using a graphing tool

The solution is the triangular shaded area

Remember that the number of tickets must be a whole number

see the attached figure
