(Please i need help) The expression p - 0.15p can be used to calculate the final cost of an item that has a price of p and is discounted 15%.
What is the final cost of an item that has an original price of $23?
Enter your answer as the correct value with two decimal places, like this: 42.53

Final cost of the item is $19.55

Step-by-step explanation:

Expression representing the final cost of an item with original price = $p and discount = 15% will be,

Final cost = (p - 0.15p)

If the original price p = $23

By substituting p = 23 in the expression given,

Final cost after discount = 23 - (0.15)23

                                         = 23 - 3.45

                                         = $19.55

Therefore, final cost of the item is $19.55

substitute,

circle 1 = 5

circle 2 = 20

circle 3 = 44

in this case no matter how you add, you will always get a perfect square..

hence proved
