On a certain hot summer’s day, 710 people used the public swimming pool. the daily prices are $1.25 for children and 2.50 for adults. the receipts admission totaled $1288.75. how many children and how many adults swam at the public pool that day?

CHILDREN= 389

ADULT=310

Step-by-step explanation:

1)A + C = 710                          2) A*2.50 +  C*1.2 = 1288.75

OR, A= 710-C                            (710-C)*2.50 + C*1.2=1288.75

                                                    1775-2.50*C+1.25*C=1288.75

                                                    1775 -1.25*C = 1288.75

                                                    -1.25*C=1288.75-1775

                                                     1.25*C=486.25

                                                     C = 486.25/1.25

                                                     C = 389

                                         Again or, A + C = 710

                                                          A = 710 - C

                                                          A = 710 - 389

                                                           A = 321

The total amount of screen needed is 22 ft^2

Step-by-step explanation:

We know that

The surface of a rectangular prism is

SA = 2B + Ph

where

B is the area of the base

P is the perimeter of the base

H is the height of the rectangular prism

Find the area of the base B

B = (3) (1) = 3 ft²

Find the perimeter of the base P

P = 2(3 + 1) = 8 ft

The height of the prism h is

h = 2 ft

substitute the values

SA = 2(3) + (8) (2)

SA = 22 ft²

So , the total amount of screen needed is 22ft^2
