Increasing it by 10% will be 11.55. To find teen percent all you do is make it a decimal then multiplying it by 10.50
100 + 0.50c = 1.50c <== ur equation

100 = c....so he would have to sell 100 cups of coffee to break even
First cut the shape into a square, triangle and rectangle. Then add all 3 areas. Area of a quadrilateral is A= b x h So once square is 4 X 4= 16. The rectangle has a area of 4 x 2= 8. The triangle, using the formula 1/2bh has an area of 1/2 x 2 x 4 = 4. So the area of the shape is 16 + 8 + 4 = 28 units
Well 1 pound should cost $3 so do the math lol
