Explanation:
Conrad correctly
answered 24
problems on his
homework, receiving a
grade of 80%. How
many problems were
in the homework?
A. 104
B. 6
C. 30
D. 192
To determine how many problems were in Conrad's homework, we can set up a proportion using the information provided. Let's denote the total number of problems as "x".
Conrad answered 24 problems correctly out of x problems, which gives us the ratio:
24/x = 80/100
To solve for x, we can cross-multiply:
80x = 24 * 100
Dividing both sides by 80:
x = (24 * 100) / 80
x = 2400 / 80
x = 30
Therefore, there were 30 problems in Conrad's homework.
