Using the change of base formula, evaluate log312 (round to the nearest hundredth).

2.26

Step-by-step explanation:

Given: log base 3 and 12

Using the base rule, we can write it as

= log 12 / log 3

Now we can find the value of log 12 and log 3 using a calculator.

= 1.07918124 /0.477121754

=2.26                

The answer is 2.26

Hope this will helpful.

Thank you.

step-by-step explanation:

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
