## Question:

Jacob has serveral babysitting jobs. On one job he earnefd $10 an hour plus an extra $20 since there where 3 children. On another job, he earned $15 an hour. He earned the same amount of money at both jobs. How many hours did he work and how much did he earn?

## Answer:

**Answer:**

Jacob worked 4 hours and earned $60

**Step-by-step explanation:**

Let

y —-> the amount earned

x —-> the number of hours

**First job**

The linear equation is equal to

y=10x+20 —-> equation A

**Second job**

y=15x —–> equation B

we know that

He earned the same amount of money at both jobs

To find the number of hours he worked math equation A and equation B

10x+20=15x

solve for x

15x-10x=20

5x=20

x=4 hours

so

For x=4 hours

y=10x+20 ——-> y=10(4)+20=$60

y=15x ————-> y=15(4)=$60

For x=4 hours

The amount earned is the same in both works

From the answer and question examples above, hopefully, they might help the student resolve the question they had been looking for and notice of all the pieces stated in the answer above.
