t is the number of hours Lamar worked as a tutor
We know that he worked for 92 hours total, so he worked 92-t hours as a waiter.
So his earnings are: 7t + 8(92-t) = 736 -t dollars
This expression seems logical as if Lamar worked 0 hours as a tutor and 92 as a waiter his earnings would be 8*92 = 736
If he worked as a tutor for 92 hours it would be 7*92= 644
736-92= 644
So our expression seems to be working.
Kevin will have enough. He will need to pay $23.10.
5% of $22 is $1.10.
22+1.10=23.10
23.10 is less than 24
1/2 or 50%
cuz there’s only two probable outcomes
