Answer:
15
Explanation:
Reasoning: First you multiply 75% of 20 which is 0.75x20 which is 15.
If you still don't get it you can see that the servers keep 75% of the tips while the support staff keep 25%
IF THERE IS 20$ TIP LEFT AT A TABLE we know we can cross out $5 and $20 because they are not reasonable.
so it is left between $10 and $10 you can also do 15/20 which is 0.75
but if you do 10/20 the answer is 0.5.
So option c $15 is correct.
P.S there is a typo for $5 there is two but on edge there is only one $5.
pls have a great day!!!!
