Answer: 4.2 yards
Step-by-step explanation:
Let x = length of the Flores' lawn in yards.
Then, Area of lawn = 4x sq. yard [Area of rectangle = width x length , here width = 4 yds (given)]
Charge per square yard = $1.25
Charge for Flores lawn = 1.25 × (Area of lawn)
= 1.25 (4x)
= 5x
As per given,
Hence, the length of the Flores's lawn = 4.2 yards
Answer:
Third option i.e. A. and B. About 4,323 people
Step-by-step explanation:
We are given that,
Initial population of the town = 2,700
The rate of growth = 4% = 0.04
Part A: Since, the equation for the growth is given by,
Population growth = , where P is the initial population, r is the rate of growth and x is the time period of growth.
We have, according to the question,
Population growth =
i.e. Population growth =
Thus, the equation for the population growth is .
Part B: Now, it is required to find the population after 12 years i.e. x= 12.
So, we have,
Population =
i.e. Population =
i.e. Population =
i.e. Population = 4,323
Hence, the population after 12 years is 4,323 people.
Thus, the third option is correct.
