Final answer:
The student worked 150 hours as a waiter and 50 hours as a cook over the summer. We derived this by creating a system of equations using the provided pay rates and total earnings, and then solving for the number of hours in each job.
Step-by-step explanation:
To solve the problem about how many hours a student worked as a waiter and how many as a cook, we need to create a system of equations based on the information given:
- The student worked a total of 200 hours over the summer.
- The student worked some hours as a waiter at $6 per hour and some as a cook at $8 per hour.
- The student made a total of $1300 over the summer.
Let w be the number of hours worked as a waiter and c be the number of hours worked as a cook. We can then express the situation with the following equations:
w + c = 200
6w + 8c = 1300
To solve this system, we can use either the substitution or the elimination method. For illustration, we will use the substitution method:
- Express w in terms of c from the first equation:
w = 200 - c. - Substitute this expression for w into the second equation:
6(200 - c) + 8c = 1300. - Simplify and solve for c:
1200 - 6c + 8c = 1300
2c = 100
c = 50. - Now substitute c = 50 into the expression for w:
w = 200 - 50
w = 150.
So, the student worked 150 hours as a waiter and 50 hours as a cook.
