Answer:

mp=4500

let discount %be x

sp=mp-discount %of mp=4500-x/100×4500=4500-45x

Step-by-step explanation:

sp with 10%vat=sp+vat%of sp

4400=4500-45x+10/100(4500-45x)

4400-4500=(-450x+(4500-45x)/10

-1000=(-450x+(4500-45x)

-1000-4500=-495x

495x=5500

x=5500/495=11.11%

The population size after 6 years and after 8 years are 147 and 169 population respectively

<h3>Exponential functions</h3>

The standard exponential function is expressed as y = ab^x

where

a is the base

x is the exponent

Given the function that represents the population size P (t) of the species as shown;

$p(t)=\frac{550}{1+5e^{-0.1t}} \\$

For the population size after 6 years

$p(t)=\frac{550}{1+5e^{-0.1(6)}} \\P(6)=\frac{550}{3.744}\\ P(6)=147 population$

For the population after 8 years

$p(t)=\frac{550}{1+5e^{-0.1(8)}} \\P(8)=\frac{550}{3.2466}\\ P(8)=169 population$

Hence the population size after 6 years and after 8 years are 147 and 169 population respectively
