Automobile sales in a country were 35.9 million this year, a 2.4% increase over last year. find the number of auto sales in the country last year.

35,058,593.75

Step-by-step explanation:

let the number of sales for last year be x

2.4% increase is given as (2.4/100 * x)

x + 2.4x/100 = 35900000

finding the lcm of the right side

(100x + 2.4x)/100 = 35900000

102.4x/100=35900000

multiplying both sides by 100 and dividing by 102.4 gives

x = (35900000 * 100)/102.4

x =  35,058,593.75

step-by-step explanation:

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
