A lunch in a fancy restaurant is three times as expensive as a lunch in a cafeteria. The lunch in the fancy restaurant costs P36. In a 5-day workweek, Mary eats at the fancy restaurant once, and in the cafeteria the rest of the days. How much does she spend on lunches in that week?
since in a fancy resturant is 3 times as expensive as a lunch in a cafeteria. 36 divided by 3 to get the amount of lunch in the cafeteria which is 12. 36+12+12+12+12+12+12= 108 she spend 108 in that week for her lunch.
