Since the donations are in ratio 4:4:7 they can be represented by 4x, 4x, and 7x, where is x is unknown.
The total amount is $75 means:
3x + 3x + 7x = 75
13x = 75 divide both sides by 13
x = 75/13
The smaller donations are:
4*(75/13) = $23.08
The largest donation is:
7*(75/13) = $40.38
The largest donation is greater by $40.38 - $20.08 = $17.30 than the smaller donation.
