Answer:
60 feets 
Step-by-step explanation:
Given that :
Using Pythagoras rule :
Hypotenus = sqrt(Adjacent^2 + opposite^2)
From the attached picture :
x² = 87^2 - 63^2
x^2 = 7569 - 3969
X^2 = 3600
Take the square root of both sides :
X = sqrt(3600)
X = 60 feets
Hence, Katy and Tony are 60 feets apart
 
        
             
        
        
        
Answer:
The student added the discount instead of subtracting the discount.
They also did not calculate the tax correctly.
Step-by-step explanation:
Original price is 499
Discount = original price * percent off
Discount = 499 * .18
                =89.82
The sale price = original price minus the discount
sale price = 499-89.82
sale price = 409.18
Sales tax = sale price * tax rate
                 = 409.18 * 8.875%
                 =409.18*.08875
                  =36.314725
Rounding to the nearest cent
                      36.31
Final cost = sale price + sales tax
                   =409.18+36.31
                    445.49
The student added the discount instead of subtracting the discount.
They also did not calculate the tax correctly.
