A city has a population of 390,000 people. Suppose that each year the population grows by 5.5%. What will the population be after 7 years?
Use the calculator provided and round your answer to the nearest whole number.

Exponential growth formula:

Total = start value x ( 1 + percentage)^ time

Total = 390,000(1+ 0.055)^7

Total = 390,000(1.055)^7

Total =567,324.87

Rounded = 567,325

step-by-step explanation:

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".
