Answer:
a). 200y + 350(50 - y) = C
b). [tex]y=\frac{17500-C}{150}[/tex]
C). 15 children going on the trip.
Step-by-step explanation:
This question is incomplete; here is the complete question attached.
a). One month, total trips sold = 50
Out of these trips, number of trips sold for children = y
Cost of a trip for child = $200
Total cost of y trips of children = $200y
Number of adult trips = (50 - y)
Cost of each adult trip = $350
Total cost of the adult trips = $350(50 - y)
If travel agency collected the money by selling these trips = $C
So equation representing this phenomenon will be
200y + 350(50 - y) = C
b). 200y + 350×50 - 350y = C
17500 - 150y = C
[tex]y=\frac{17500-C}{150}[/tex]
C). For C = $15250
[tex]y=\frac{17500-15250}{150}[/tex]
[tex]y=\frac{2250}{150}[/tex]
y = 15 trips
Therefore, 15 children are going on the trip.
