507 people used the public swimming pool , the daily price for children is 1.75 and the price for adults was 2.25 and the admission total was 971.75 how many children were at the public pool ?

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

after simplifying it i got: -36.25 as my answer. hope that !
