Simplify the expression using the order of operations. 3×(3+12÷3)−4

17

Step-by-step explanation:

Hey there !!!

for this question we use the PEDMAS rule which stands for  

Parenthesis, Exponents, Divison, multiplication, Addition, and Subtraction

Step 1: solve the equation in the Parenthesis

3×(3+12÷3)−4

in parenthesis problem = 3+12÷3

divide first 12÷3 = 4

then add 4+4 = 7

Step 2: Do mutipliction

3×7-4

in the PEDMAS rule, it said to do multiplication before Addition

so, 3×7-4

multiplication part = 3×7 = 21

Step 3: Do Subtraction

21-3

now we do subtraction because it is the last step and it is also in the PEDMAS

21-3= 17

3×(3+12÷3)−4 = 17

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
