Bob and Johnny have a leaf raking business. They charge $4 for each bag of leaves they rake. On Monday they raked 5 bags of leaves. On Tuesday they raked 3 bags of leaves. On Wednesday, they counted their money and found they had $68 for all three days. How many bags of leaves did they rake on Wednesday? Let's be accurate as possible.
Combining Monday and Tuesday, they raked 5 + 3 = 8 bags of leaves. They earned 8 * $4 = $32 for the first two days. O for Wednesday's work they earned $68 - $32 = $36. Thus, they raked $36 / $4 = 9 bags of leaves on Wednesday.
The answer: 9.
