Answer
They will each make $21.
Step-by-step explanation
We are told that Drew's neighbor pays him $35 to mow her lawn and she always gives a 20% tip
So, the amount Drew would get in total will be
= $35 + (20% × $35)
= $35 + $7
= $42
So, if Drew mows the lawn with his friend, and splits the earnings evenly, they will be splitting $42 between 2 of them
That is, ($42/2) = $21 per person.
Hope this Helps!!!
