Number of cookie boxes bought by James = 5 Number of cakes bought by James = 2 Cost of each cakes = $4 Total bill paid by James = $28.50 Let us assume the cost of the each boxes of cookies = x Then 5x + (2 * 4) = 28.50 5x + 8 = 28.50 5x = 28.50 - 8 5x = 20.50 x = 20.50/5 = 4.10 So we can see from the above deduction that the cost of each boxes of cookies bought by James is $4.10
The answer is HL. HL is a theorem stating that if the hypotenuse and one leg are congruent to another pair of hypotenuse and leg then the triangles themselves are congruent. Hope this helps.
