<span>If Tanya’s three items (x) cost the same as Tony’s four items (y), 3x = 4y. Y is 2.25 less than x, so: 3x = 4x - 4 x 2.25. 3x = 4x - 9. 3x + 9 = 4x. 9 = x. Therefore, y = 9 - 2.25. x = 9 and y = 6.75. Three times 9 and four times 6.75 is 27. Tanya’s items cost $9 each and Tony’s cost $6.75.</span>

Step-by-step explanation:
The area of a shape is the amount of space it can occupy.
<em>The number of isosceles triangle in the grid is: </em>
<em />
The dimension of the grid is given as:

Calculate the area


The area of each isosceles triangle is given as:

The number (n) of the triangle in an x-by-x grid is:

So, we have:

Express as products


Hence, the number of isosceles triangle in the grid is:
