Answer:

A) 12 + 3g < 50

B) He can get 10 or 12 gallons but not 13.

C) Graph with open circle on 12.67 on number line with the arrow pointing left or less than.

Step-by-step explanation:

To write the inequality, use the numbers given in the word problem. Luis will pay $12.00 for a car wash plus $3.00 per gallon and it must be less than $50.

12+3g < 50 where g is the number of gallons purchased.

Solve for g using inverse operations.

12-12+3g < 50-12

3g < 38

g < 12.67

This means Luis must buy less than 12.67 gallons to spend less than $50.
