Answer:
Zamir 75%
Caleb 72%
Rosa 76%
Work
<u>Zamir</u>
.75=75%
75*40=3000
3000/ 100= 30
<u>Zamir got 30 out of 40</u> questions right
<u>Caleb</u>
30-12=18
<u>Caleb got 18 out of 25</u> questions right now find percent
18*100=1800
1800/ 25= 72
Caleb got 72%
<u>Rosa</u>
18+1=19
<u>Rosa got 19 out of 25 </u>questions correct now find percent
19*100=1900
1900/ 25=76
Rosa got 76%

Step-by-step explanation:
Using a system of equations, it is found that Debbie worked 45 hours during the week.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
- Variable x: Amount of hours worked by Juan.
- Variable y: Amount of hours worked by Debbie.
Juan and Debbie each earn 9 per hour at their "jobs", and earned a total of 765 for the week, hence:
9x + 9y = 765
Simplifying the expression by 9:
x + y = 85 -> x = 85 - y.
Debbie worked five hours more than juan during the week, hence:
y = x + 5.
Since x = 85 - y, we replace in the expression:
y = 85 - y + 5.
2y = 90.
y = 45.
Debbie worked 45 hours during the week.
