Suppose the population of a town is 9,800 and is growing 2% each year. a. write an equation to model the population growth. b. predict the population after 7 years. y = 9,800 • 1.02x ; about 11,257 people y = 2 • 9,800x ; about 137,200 people y = 9,800 • 2x ; about 11,257 people y = 9,800 • 2x ; about 1,254,400 people

 First option is correct.

Population after 7 years becomes 11257.

Step-by-step explanation:

Since we have given that

Number of population of a town = 9800

Rate of growth = 2%

Number of years = 7

We need to find the number of population after 7 years:

So, It becomes,

Hence, First option is correct.

Population after 7 years becomes 11257.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
