Answer:
Step-by-step explanation:
12.3 + 9.6 = 21.9
100% of the price = $400
x % of the price = $320
we need to find x
using a proportion
100 : 400 = x : 320
100 * 320 = 400 * x
32000 = 400x
x = 32000 / 400
x = 80
That means the new price is 80% of the previous price.
100% - 80% = 20%
and based on this we can make a conclusion that the discount was 20%
I hope it is clear to you, feel free to ask anything about it :)

Answer: 30 trees
Step-by-step explanation:
Elizabeth has 330 citrus trees and 180 palm trees
The largest number of trees that she can have in a row will base on the highest common factor between the two number of trees
330 = 2 × 3 × 5 × 11
180 = 2 × 2 × 3 × 3 × 5
HCF = 2 × 3 × 5
HCF = 30
The largest number of trees that she can have in a row is 30 trees.
