Simplify the expression using the order of operations show all your work 150- (4²+4) ÷ 2

65

Step-by-step explanation:

150-(4^2+4)/2

150-(16+4)/2

150-(20)/2

130/2=65

140

Step-by-step explanation:

P: parenthesis

E: exponents

M: multiply

D: Division

A: add

S: subtract

150-(4^2+4)/2              exponent first 4^2= 4*4=16  you do this because it is                              

                                              inside the parenthesis

150-(16+4)/2                you still have parenthesis so solve that next

150-20/2                     next you divide because there is no multiplication

150-10                         then subtract because there is no addition

140   is your final answer

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
