The population of a certain country is approximated by the following equation, where x is the number of years since 1980 and P is the population in millions. P= 2.726x + 126.189

235

Step-by-step explanation:

The population equation is given as P= 2.726x + 126.189

-To find the number of years since 1980, we subtract the start year from the current year(2020):

X=2020-1980=40

We substitute the x value in the population equation to find the current population:

P=2.76x+126.189 but x=40

P=2.76(40)+126.189=235.229

Rounding off then the population in the current year is 235

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88
