Answer:

The admixture of words and math symbols must be rewritten to allow processing towards a correct answer.

Step-by-step explanation:

Use brackets [ ] and up carrot symbol (^, obtained by pushing the shift key at same time as 6 key) to rewrite the question. The order of operations called GEMA (Grouping, Exponents, Multiplication and Division from left to right and then Addition and Subtraction from left to right) can only be done once the symbols are placed to match the textbook question. Math is a language and its symbols must be used in place of words to assure the correct result.

Steven wants to increase the number of books he reads per year. He currently reads 2 books a year. He wants to triple the number

Sladkaya [172]

Answer:

$B=2\times 3^n$

Step-by-step explanation:

<u>Exponential Growing </u>

Steven currently reads 2 books a year. He wants to triple the number of books read per year. The first year he should read

$2*3 = 6\ books$

By the second year, he should read

$2*3^2 = 18\ books$

By the third year, he should read

$2*3^3 = 54\ books$

We can clearly see there is a geometric progression of the number of books he should read for the year n. The general formula is, being B the number of books read at the year n

$\boxed{B=2\times 3^n}$
