One equation that gives the estimated number of free throws (all the 3 people) is 77 out of 120. The best player will make about 56 out of 80 free throws.
Answer and explain: 1st person: 70% throws 70/100x80 = 56 out of 80 throws 2nd person: 60% throws 60/100x80 = 48 out of 80 throws 3rd person 50% throws 50/100x80 = 40 out of 80 throws 56+ 48+40/80x3 = 77/120 One equation that gives the estimated number of free throws (all the 3 people) is 77 out of 120. The best player will make about 56 out of 80 free throws.
All you have to do is divide the left side of the ratio by 5 and the right side of the ratio by 7. The one that comes out even on both sides is the correct one.
