Assuming she only uses the car for one day 200 miles

52-22=30
30/0.15=200

(If she uses the car for more days do 22 x # of days and then subtract it from 52, then divide that answer by 0.15)

ankoles [38]

Answer:

4 students

Step-by-step explanation:

The total number of students is given by:

$|A|+|B|+|C|-|A\cap B|-|A\cap C|-|B\cap C| + |A\cap B \cap C| = N$

Where N is the total number of students, A is the number of students that have taken Math 2A, B is the number of students that have taken Math 2B, and C is the number of students that have taken Math 2C:

$|A|+|B|+|C|-|A\cap B|-|A\cap C|-|B\cap C| + |A\cap B \cap C| = N\\51+80+70-15-20-13 + |A\cap B \cap C| = 157\\ |A\cap B \cap C| =4$
