Kaylee is working till summer jobs making six dollars per hour walking dogs and $13 per hour landscaping. Last week kaylee worked a total of eight hours and earned a total of $83. Determine the number of hours kaily worked walking dogs last week in the number of hours she worked landscaping last week

the number of hours that Kaylee worked walking dogs last week is 3 hours.

the number of hours that Kaylee worked landscaping last week is 5 hours.

Step-by-step explanation:

Let x represent the number of hours that Kaylee worked walking dogs last week.

Let y represent the number of hours that Kaylee worked landscaping last week.

Kaylee is working two summer jobs making six dollars per hour walking dogs and $13 per hour landscaping.

Last week, she earned a total of $83. It means that

6x + 13y = 83- - - - - - - - - - - -1

Last week kaylee worked a total of eight hours. It means that

x + y = 8

Substituting x = 8 - y into equation 1, it becomes

6(8 - y) + 13y = 83

48 - 6y + 13y = 83

- 6y + 13y = 83 - 48

7y = 35

y = 35/7

y = 5

x = 8 - y = 8 - 5

x = 3

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.
