Question

Tom, Scott and dawn sold cookies at the school fair. Tom had 90 cookies and sold 60% of them. Scott had 150 cookies and sold 2/3 of them. Dawn sold 46 cookies. What percentage of the cookies sold were sold by dawn

Answer 1

Tom sold 0.60*90 = 54 cookies.
Scott sold (2/3)*150 = 100 cookies.
Dawn sold 46 cookies.

Altogether, 54 +100 +46 = 200 cookies were sold.

Dawn sold 46/200 = 23/100 = 23% of the cookies sold.
