Answer:
a = 11
Step-by-step explanation:
distribute and combine like terms
6a + 18 = 4a + 40
2a = 22
a =11
To do this you want to first multiply 28 by 0.15. This will give you $4.20. You have to give a $4.20 tip. The total cost would be the lunch and the tip added together. It would give you a final total of $32.20.
Isolate "x" on one side of the algebraic equation by dividing the number that appears on the same side of the equation as part of "x."
