(8b + 7) + (6x – 4) + (5C + 8)

8b + 11 + 6x + 5c

Step-by-step explanation:

(8b + 7) + (6x – 4) + (5C + 8)

8b + 7 + 6x - 4 + 5c + 8

8b + 11 + 6x + 5c

=6x+8b+5C+11

Step-by-step explanation:

(8b+7) + (6x-4) + (5C+8)

Remove parentheses (a) = a

=8b+7+6x-4+5C+8

Group like terms

=6x+8b+5C+7-4+8

Add Subtract the numbers 7-4+8=11

=6x+8b+5C+11

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
