Every eight years in January, the population of a town in Danbury is recorded. In 1995, the town
had a population of 4,500 people. From 1995 to 2003, the population increased by 15%. From 2003 to 2011, the population decreased 4%. What was the town’s population in 2011?
a. 4,527 b. 4,968 c. 4,995 d. 5,382

b

Step-by-step explanation:

first we need to find 15% of 4,500

0.15*4500=675

4500+675=5175

5175 people in 2003

2) next we need to find 4% of 5175

5175*0.04=207

since the pop. decreased we need to subtract 207 from 5175:

5175-207=4968

4,968 people in 2011

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
