Answer:
The correct answer is 3 hours and 25 minutes.
Step-by-step explanation:
First we must analyze the information we have:
We know that for 1 hour of yard work, Conor earns $ 9
Now what we want to know <u>is how many hours he will have worked if he earned a total of $ 29.25.
</u>
And one of the ways we can find out would be with a cross-multiplication:
1 hour ----- 9
x hours ---- 29.25
Then we multiply crosswise:
1 . 29,25 = 9.x
29,25 / 9 = x
3,25 = x
Therefore, the correct answer is 3,25.
