Step-by-step explanation:
<u>We have similar triangles here.</u>
- BC║DE, AB║AD and AC║AE ⇒ ΔADE ~ ΔABC
<u>The ratio of corresponding sides of similar triangles is same:</u>

- BC / 2 = 30/3
- BC / 2 = 10
- BC = 2*10
- BC = 20 m
7.1% subtract the final price by the original price to find the increase and then divide the increase by the original price.
Explanation:
Find the increase
3.75−3.50=.25
Then divide the increase by the original amount
.253.50=.0714285
To change to a percent multiply by 100 and round off to significant numbers
# .0714285 = 7. 14285% or 7.1% or just 7%
