Eight times a number equals 24 more than two times the number. what is the number

4

Step-by-step explanation:

I'll use  n  to represent the unknown number.

8 n  = 24 + 2 n

→ times means multiplication (8 times a number  n  means  8 ⋅

n  or  8 n  ,the same thing goes for 2 times the number), 24 more than  2  n  indicates that  2 n  is being increased by 24 ( 24 + 2 n )

6 n = 24 n = 4

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
