Answer 1

5hrs landscaping and 3hrs walking dogs

Answer 2

The correct answer is 3 hours walking dogs and 5 hours landscaping.
Explanation:
Kaylee is working two summer jobs, making $6 per hour walking dogs and $13 per hour landscaping.
Total number of hours Kaylee worked last week is 8. Let Kaylee worked for x hours walking dogs and the remaining 8 - x hours landscaping.
Amount earned walking dogs last week = $6x.
Amount earned landscaping last week = $ 13 (8 - x).
Total amount given that Kaylee earned is $83.
∴ 6x + 13 (8 - x) = 83
⇒ 7x = 21
⇒ x = 3
Therefore Kaylee worked for 3 hours walking dogs and 5 hours landscaping last week.
