Agift shop buys greeting card $3.50 each and sells them at 80% mark up. at what price dose the gift shop sell each greeting card?

3.50 x 80%* = 2.8  2.8+3.50=6.30
I hope this helps!!!

(0.8)

You can find the area of a rectangle by multiplying the length and height. so multiply 1/2*7/4(which is the simpler version of 1 3/4) and you get 7/8 as your answer.
