Suppose the population of a town is 9,800 and is growing 2% each year. write an equation to model the population growth. predict the population after 7 years.

y = mx + b

y = population after x years

m = rate of change

x = years

b = initial population

First, we have to figure out how much the population grows per year. To do this, we have to find 2% of 9800.

2% = 0.02

(0.02)(9800) = 196

The population grows 196 people per year.

y = 196x + 9800

y = 196(7) + 9800

y = 1372 + 9800

y = 11172

The population after 7 years will be around 11, 172 people.

Hope this helps!

the range is 19

step-by-step explanation:

the range is biggest number minus the smallest, so in this case it would be

41 - 22 = 19

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
