<span>Each smaller donation was for $20 The largest donation was $15 greater than the smaller donation. First, determine the size of each donation. Since they are in a ratio of 4:4:7, it's easiest to add the ratios together (4+4+7) = 15. Then divide the total donation by that sum (75/15) = 5. Finally, multiply 5 by each of the ratios. 5 * 4 = 20, 5 * 4 = 20, and 5 * 7 = 35 So the 2 smaller donations were $20 each, and the largest donation was for $35. The largest donation was $35 - $20 = $15 larger than one of the smaller donations.</span>

Please help<br><br> -3/4(8n + 12) = 3(n-3)
Dennis_Churaev [7]

Step-by-step explanation:

-  \frac{3}{4} (8n + 12) = 3(n - 3)

- 3(8n + 12) = 12(n - 3)

\cancel{- 3}(8n + 12) =  \cancel{12}(n - 3)

- (8n + 12) = 4(n - 3)

- 8n - 12 = 4n - 12

- 8n - 4n =  - 12 + 12

- 12n = 0

n = 0
