Heather is a hairdresser and her customers pay $5 to reserve an appointment time and $12 for every hour Heather works on their hair style. As a back to school special she offers to lower her price per hour by $5. What equation represents the total amount paid to Heather, y, after x hours of hair styling?

Mrs. Schmidt's family bought lunch from Culvers.  They also bought some sodas from Quick Trip for $5.00. The meals cost $6.00 each. The total cost of the lunch and soda was $41.00. Let x represent the cost of the number of meals that Mrs. Schmidt bought. Write the equation and solve for x.

• -5+6x = 41, 4 meals
• 6x + 5 = 41, 6 meals
• 6x = 36 meals
• 5 + 6x = 41, 7 meals
