Compute the total cost of the meal to the nearest cent: meal costs $29.78 plus 5% tax and 15% tip.

tresset_1 [31]

To solve this problem you must apply the proccedure shown below:
1. You have the following information given in the problem above: <span>$29.78 plus 5% tax and 15% tip.
2. Therefore, you have:
Total=$29.78+(0.05)($29.78)+(0.15)($29.78)
3. Then, the result is:
Total=$35.74
Therefore, as you can see, the answer is the option D, which is: D. $35.74</span>

Answer:

Step-by-step explanation:

So we have the piecewise function:

$f(x)= \begin{cases}\sqrt{2x} & \text{if }x$

And we want to find f(8).

Since our input value is 8, choose the equation that fits our input.

The first equation demand x to be less than 3. 8 is not less than 3, so we won't use that.

The second equation demand x to e greater than or equal to 3 and less than 8. 8 is <em>not</em> less than 8. So, we won't use that.

The third equation demands x to be greater than or equal to 8. 8 is greater than or equal to 8, so we'll use the third equation.

So:

$f(x)=42\text{ if }x\geq 8$

$f(8)=42$

There're nothing more to do, we're done :)

The answer is A.
