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

  answer:

  write 548 as 500 + 40 + 8. multiply each addend by 5. then add the three products to get 2,740.
