Their earnings would be the same after 4 hours
Let the number of hours be x, and the weekly earning be y
So, the given parameters are:
<u>Kimi</u>
- Earnings = $9 per hour
- Weekly allowance = $8
So, the equation for Kimi's weekly earning is:
![y =9x + 8](https://tex.z-dn.net/?f=y%20%3D9x%20%2B%208)
<u />
<u>Jordan</u>
- Earnings = $7 per hour
- Weekly allowance = $16
So, the equation for Jordan's weekly earning is:
![y = 7x + 16](https://tex.z-dn.net/?f=y%20%3D%207x%20%2B%2016)
Equate both equations
![7x + 16 = 9x + 8](https://tex.z-dn.net/?f=7x%20%2B%2016%20%3D%209x%20%2B%208)
Collect like terms
![9x - 7x = 16 - 8](https://tex.z-dn.net/?f=9x%20-%207x%20%3D%2016%20-%208)
![2x =8](https://tex.z-dn.net/?f=2x%20%3D8)
Divide both sides by 2
![x =4](https://tex.z-dn.net/?f=x%20%3D4)
Hence, their earnings would be the same after 4 hours
