Answer:

1018.

Step-by-step explanation:

The multiplying factor here is 1 +0.09 = 1.09. Every year the current population figure is multiplied by 1.09. We have 10 years of growth so:

  P(2010) =  430(1.09)^10

= 1018.

the sale price of an iphone is 179.00. if the percent discount was 20% what was the original price of the iphone?
Tju [1.3M]
100 - 20 = 80
179.00 = 80%
179.00 / 80 = 2.2375 = 1%
1% x 100 = 100%
So, 2.2375 x 100 = 100%
Therefore the original price was 223.75
