13 is 26% of what number

50

Step-by-step explanation:

13/50

Step-by-step explanation:

We already have our first value 13 and the second value 26. Let's assume the unknown value is Y which answer we will find out.

As we have all the required values we need, Now we can put them in a simple formula below:

13 = 26% x Y

13 = 26/100 x Y

Y = 13  x 100/26

Y = 13 x 100 / 26

y = 50

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
