You collect a total of $80 from 3 people. the 3 donation are in the ratio 3 : 3 : 10.how much do the two people that donate the same amount spend. also how much larger is the largest donation than the smaller donations.

The ratio is 3 to 3 to 10. We can translate this to algebra with a replacement that the 3 people each donate 3x, 3x, and 10x dollars respectively. Adding these 3 variables together, we get that the total collected is 16x dollars, which is equal to 80 dollars. Therefore, each unit x donation from each person is 5 dollars. Therefore, the two people that donated the same amount would have donated 15 dollars each (3x = 3 *5). The largest donation of 10x = 5*10 = 50 dollars is 50 -15= 35 dollars larger than the smaller donations.

The answer to your question is b’(16,14)
