During October, a store had sales of $30,000. If this was a 20% increase over the September sales, what were the September sales?? Please include the solution... Thank you..



Sagot :

30000 divided by 100 = 300 per 1%
300 x 20 =6000
30000 + 6000 = 36000
$30,000 times 1.2(short for 120 %[in decimal form 1.2])
=$30,000
 *       1.2
 $36,000
The sales in September was $36,000
