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. a. y = 9,800 • 1.02x ; about 11,257 people b. y = 9,800 • 2x ; about 11,257 people c. y = 9,800 • 2x ; about 1,254,400 people d. y = 2 • 9,800x ; about 137,200 people

The correct option is A.

Step-by-step explanation:

The general exponential growth model is defined as

Where, a is initial value, r is growth rate and x is time.

The initial population of town is 9800 and growth rate is 2%. The population growth model is defined as

Put x=7 to find the estimated population after 7 years.

Therefore the correct option is A.

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
