this is simple, but i think I'm not using the correct value....
A store reported total sales of $385 million for February of this year. If the total of sales for the same month last year was $320 million, approx what was the percent increase in sales?
a) 2%
b) 17%
c) 20%
d) 65%
e) 83%
I thought it was the increase divided by the original times 100%. I had 65/320. Did I not work the math correctly? Or did I use the wrong values? Anyone?
