Answer:
The linear equation for tip barista gets in a day is f(n)=0.5n+20.
Step-by-step explanation:
It is given, at a noon a barista notice that she has $20 in tip jar, if she makes an average of $0.50 from each customer,
It is required to find how much will she have in her tip jar if she serves n more customers during her shift. m=0.5. Bases on this write the equation for n more customers.
Step 1 of 1
It is given, at a noon a barista notice that she has $20 in tip jar, if she makes an average of $0.50 from each customer,
To solve this let f(n) is the total tip barista has in her tip jar after a day.
When n is equal to 0 , that barista has $20,
Then if barista make 0.5 from each customer, then for the linear function m=0.5,
Bases on this write the equation for n more customers,

1. 8 divided by 6
2. 6 people eat six parts and 2 parts are left over
