You collect a total of $75 in donations from three people. The three donations are in the ratio 4 : 4 : 7.

1 answer:

7 0

75 in donations...ratio of 4:4:7....added (4+4+7) = 15

4/15(75) = 300/15 = 20 <==
4/15(75) = 300/15 = 20 <==
7/15(75) = 525/15 = 35 <==

the smaller donation is $ 20
the larger donation is $ 15 greater then the smaller donation
