Answer:
The correct answer is - 17.
Step-by-step explanation:
Given:
total students = 219
in chemistry = 112
in physics = 45
not enrolled in either of these = 79
solution:
The number of students in both classes can be calculated by
P ( A or B) = P (A) + P (B) - P (A and B)
then putting and solving the given vaues in formula
=> (219-79) = 112+45-x
=> 140 = 157 -x
=> 17 = x
Graph B..................................................................
C = Cost ($)
m = Miles driven {m≥100}
d = Rental days
---------------
Use this formula if m≥100:
C = 36 * d + 0.5 * (m - 100)
Use this formula if m<100:
C = 36 * d
