At a travel agency the cost of a trip is $350 for adults and $200 for a child. One month the agency sold 50 trips. Of these trips , y trips were for children. The travel agency collected c dollars for selling all 50 trips.

a). 200y + 350(50 - y) = C

b).

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

C). For C = $15250

y = 15 trips

Therefore, 15 children are going on the trip.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
