The admission fee at an amusement park is $20 for children and $35 for adults. on a certain day 247 people entered the park, and the admission fees collected totaled $6965. how many children and how many adults were admitted

 112 children & 135 adults

Step-by-step explanation:

            #        $    

Child:     x         20x

Adult:    y          35y

Total:   247     6965

#:      x +    y =    247   →   -20(x + y = 247)         →   -20x - 20y = -4940

$: 20x + 35y = 6965  →   1(20x + 35y = 6965)  →   20x + 35y = 6965

                                                                                            15y  = 2025

                                                                                                y  =  135

Substitute y = 135 into either of the original equations to solve for x:

x +   y = 247

x + 135 = 247

      x  = 112

step-by-step explanation:

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
