Target purchases of sharpie markers for 2.50 each. They sell these same markers in the store with a markup of 150%. How much is
11111nata11111 [884]
Well to find out you multiply 2.50 by 2.50. You multiply the original price by 2.50 because they resell the marker packages for 100%, the original price with an additional 150% so 1.00+1.50=2.50
2.50 * 2.50 = 6.25
So target charges $6.25 for a package of sharpie markers.
