Hi Luke,
Per "cent" means "per hundred" (think of 100 cents in a dollar). So, 37% of 100 is 37. And, 50% of 320 is 160. So, how do we find out what present of 320 the number 112 will be?
We divide 112/320 = x/100 (read this as 112 out of 320 is x percent of 100)
100*(112/320) = x (multiply both sides by 100)
35 = x (do calculations)
So, 35% of the salesman's calls resulted in a sale.
