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.

Factoring Trinomials
alexandr402 [8]
25 a² + 20 ab +  4 b²

for formula a^x+bx^ky^k+cy ^{2k } find  u,v such that: u.v = a

and u+v = b  then  group according to (ax ^{2k} +ux^ky^k)+(vx^ky^k+cy ^{2k} )

= (25a^2+10ab)+(10ab+4b^2)

factor out 5a from : 25a^2+10ab : 5a(2b+5a)

factor out 2b from : 10ab+4b^2: 2b(2b+5a)

= 5a(2b+5a) + 2b(2b+5a)

factor out : (5a+2b)

= (5a+2b)(5a+2b)

Refine:

(2b+5a)^2

hope this helps!.
