Answer:

b = 55°

c = 35°

Step-by-step explanation:

b° = 180° - (85°+40°) = 180° - 125° = 55°

c° = 180° - (b°+90°) = 180° - (55°+90°) = 180° - 145° = 35°

The admission fee at a fair is $2.00 for children and $4.00 for adults.

On Saturday 2,500 people entered the fair and $7,000.00 were collected.

How many children and how many adults attended? Give your answer, using x for children, y for adults.

Form of: x =, and y =

 

Let K = no. of children

Let A = no. of adults

 

2500 people mean

Kids + Adults

 

K + A = 2500

K = 2500 – A

 

2K + 4A = 7000

K + 2A = 3500

 

(2500 – A) + 2A = 3500

A = 3500 – 2500

(A = 1000, adults)

 

K = 2500 – A

K = 2500 -1000

(K = 1500, Kids)

 

CHECK:

1500*2 = $3000

1000*4 = $4000
