Ms. Jacobs is a photographer .  For each job she charges $135 for the first hour she works and $100 for each additional hour.  Ms. Jacobs charged $535 for a job she completed.  Write an equation that can be used to determine the number of hours (h) she spent on the job.

• 135x + 100 = 535
• 100x - 135 = 535
• 100x + 135 = 535
• 135x - 100 = 535

 A computer printer can print 10 pages per minute. There were already 35 pages in the tray.  The total pages printed was 115 pages.  Write an equation to represent the number of pages the printer can print in m minutes. 

• 10m + 35 = 115
• 10m - 35 = 115
• 115m + 35 = 10
• 35m + 10 = 115

An electrician charges $90 per hour along with a $60 traveling fee.  If your bill was $600, write an equation that can be used to determine how many hours (h) it took the electrician to complete the job.

• 60 - 90h=600
• 90h + 60 = 600
• 60h + 90 = 600
• 60h - 600 = 90

The steps in solving 5b - 6 = 24 are: 

• Add 6 to both sides and divide both sides by 5
• Add 6 to both sides and multiply both sides by 5
• Subtract 6 from both sides then multiply both sides by 5
• Subtract 6 from both sides then divide both sides by 5
