Two hundred college students were asked where they buy their lunches. The results showed that 84 students buy their lunches in the food court in the university center, 101 students buy their lunches from a food truck and 28 students buy their lunches from both. Based on the survey, how many students buy lunch:

Answer

The students buys the lunch = 157

Step-by-step explanation:

Students buy their lunches in the food court in the university center = 84

Students buy their lunches from a food truck = 101

Students buy their lunches from both = 28

Students buy their lunches either from the food court in the university center or from a food truck = (Students buy their lunches in the food court in the university center) + (Students buy their lunches from a food truck) - (Students buy their lunches from both)

⇒ 84 + 101-  28 = 157

Thus the students buys the lunch = 157

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
