Christopher has breakfast at a cafe and the cost of his meal is $36.00. Because of the service, he wants to leave a 10% tip.
Fofino [41]

The <u>cost</u> of his meal at a cafe is $36.00 and Cristofer wants to leave a <u>10% tip</u>. So to find what is his <u>total bill</u>, you have to <u>count 10% from</u> $36.00.

Note that

$36.00 -- 100%,

$x -- 10%.

Write aproportion:

\dfrac{\$36.00}{\$x}=\dfrac{100\%}{10\%}.

Then

\$x=\dfrac{\$36.00\cdot 10\%}{100\%}=\$3.60.

Therefore, the total bill consists of $36.00 for the meal and $3.60 tip:

$36.00 + $3.60 = $39.60.

Answer: $39.60

What is the domain of the function y = ln ((-x+3)/2)
erastova [34]

Answer:

The Domain is x < 3

Step-by-step explanation:

We know that ln(x) is defined for all real numbers that are greater than zero, or x > 0.

Knowing that we must make the inside of ln(x) greater than 0 so:

\frac{-x+3}{2} > 0

Multiply both sides by 2:

-x+3>0

Add x to both sides:

3 > x or x
