Answer:
Step-by-step explanation:
Use proportions.
40 over a 100 because its a percentage. Then 17.5 over X because we're using X as a variable for the unknown total, of the new price for brunch.
Then you'll just cross multiply 17.5 by 100 which is 1,750 then divide it by 40 which is $43.75.
So your answer will be $43.75.
