Answer:
102
to calculate what he spent of the calculator multiple 6.20 by 15 percent of .15 which gives you .93 cents that means 15 percent is 93 cents so you subtract that from the original to get the sale price which is 5.27. subtract this from the total he spent 107.27 and you get 102 so he spent 102 on the calculator. But thats the sale price of if, so the full price must be a little over a hundred. All i did was take 120 multiple it by .15 and figure out that its 18 dollard of meaning that the full price was 120
