Apopulation is growing continuously at the rate of 1.75% per year. find the time necessary for the population to double in size.

It will take 39.95 year to become the population double

Step-by-step explanation:

Let initially the population is P

At the rate of 1.75% after some time population is doubled

So A = 2P

We have to find the time after which population doubled

We know that

Taking log both side

n = 39.95 year

150.6

all i did was i multiplied 5.02 by 30

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
