lorenzo sold65 newspaper today. if this number is 17 more than three-fifths of his sales yesterday, how many newspapares did he sell yesterday?


Sagot :

let 'x' be the number of papers he sold yesterday
-------------------------
-He sold 65 newspaper today which is 17 more than 3/5 of his sales yesterday
3/5x + 17 = 65
3/5x = 65 - 17
3/5x = 48
3x = 48(5)
3x = 240
x = 80
------------------------
Therefore he sold 80 newspapers yesterday.
