Math 7 Equations ... Word Problem Setup

Billy shovels snow to make money in the winter. He charges a flat fee of $5 to show up for a job, and $10 per hour to shovel the snow. Billy earned $65 at his last job. Which equation represents Billy's job and the number of hours, h, it took Billy to earn his money?

• 5h + 10 = 65

• 5 + 10h = 65

• 65 + 10h = 5

• 5h + 65 = 10

Answer explanation

The answer was 5 + 10h = 65

Remember that we start by writing an "= 65" cause 65 was the largest number. Then we look for "per," "each," or "every" ... and that is the number that goes with the variable.

Sarah charges $7.25 per hour to babysit plus a one-time fee of $5 to cover gas to and from the job. Sarah recently charged the Lopez family $41.25 for a babysitting job. Which equation represents the job and can determine the number of hours, h, that Sarah worked for the Lopez family?

• 5h + 7.25 = 41.25

• 41.25 - 5 = h

• 7.25h + 5 = 41.25

• 41.25 + 7.25h = 5

Answer explanation

Did you look for "per," "each" or "every?" .... per was near the 7.25 "$7.25 per hour" ... so we needed a 7.25h
