Plug in 16 to the function:

To determine if it’s a right triangle you would use the Pythagorean theorem. A^2+B^2=C^2 <——- That’s the equation. So you have to know that the hypotenuse(c) is always the longest side. 28^2+45^2=53^2. So yes it is a right triangle.
Started with: $60
left with: $10
items bought: 20
60 - 10 = 50 < amount spent
50/20 = amount spent/items bought
= $ 2.50 < each chocolate
you can check this by multiplying the items bought and the amount each item cost to get how much you spent
20 × 2.5 = 50
Stephanie started off with 60 dollars and ended with 10 dollars
60 - 50 = 10
hope this helps :)
