Answer:
181
Step-by-step explanation:
Assuming that the 'x's' all symbolize multiplication, follow these steps.
First, begin with the innermost set of parenthesis: 3x2
This will give you the answer of six, this will now give you the new equation of:
13+[9x(6)-12]x4
Following the rules of PEMDAS (Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction), it is inferable that you must multiply before subtracting the twelve.
Perform this step: 9x6 to get the answer of 54.
13+[54-12]x4
Now, as there are still brackets, perform the bracketed information:
54 - 12 = 42
This now gives you: 13+[42]x4
Yet again, following the rules of PEMDAS, you multiply 42x4 then add the result of that to 13.
42x4 = 168
168 + 13 = 181
Therefore, this expression provides the answer of 181.
Hope this helps!

Answer:
u have to use the almighty formula
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.
