Answer:
245 free throws
Explanation:
x will be number of times Audreys makes a shot, and let y be total number of the shots.
x/y = .875
(x+13)/(y+20) = .860
Let solve for x in equation 1
x = .875y
We will plug the for x in the equation 2
(.875y+13)/(y+20)
= .860
.875y + 13
= .860y + 17.2
.015y = 4.2
y = 280
Audreys has taken 280 shots.
We will Plug that back into the equation 1 in order to find out how many Audreys made.
x/280 = .875
x = 245
Hence :
Audreys made 245 free throws
