Look at the picture.
Let |AE| = |AD| = b
We have a proportion:

Solve for y from first proportion

Substitute to the second proportion

Answer: B. 25
1. a+3a+4b=5b
2. a+3a=5b-4b
3. 4a=5b-4b
4. 4a=b
a=1/4b
(I think 1/4b is the answer) hope this helps :)
773.77*0.5=386.88 hope i helped

Step-by-step explanation:
<u>Solution-</u>
Let's assume, the rate of interest of $8000 is x%,
then the rate of interest of $17000 is (x+0.3x) =1.3x%
Interest earned by $8000,

Interest earned by $17,000,

According to the question,





∴ Rate of interest of $8000 is 1.96% and rate of interest of $17000 is (1.3×1.96) =2.55%
