What is the sales tax on a breakfast order that totals $10.50 when tax is 5%
Alecsey [184]
First, you would need to create an equation for this problem. Let x represent the unknown tax. 
\frac{x}{10.50} = \frac{5}{100}

Next, you would cross multiply. 
100x = 52.5

Now, all you would have to do is isolate the x. To do this, you would divide both sides by 100. 
x = $0.525

I hope this helps!

Clare analyzes oil prices in her economics class. She finds that the mean oil price between 1988 and 2002 is $27 per barrel with
avanturin [10]

Answer:

Option 2: 1.5 is the correct answer.

Step-by-step explanation:

Given information is:

Mean = μ = $27

SD = σ = $5.50

A z-score simply tells us how far a selected data value from the mean is.

Z-score is denoted by z and is given by the formula:

z = \frac{x-mean}{SD}

Let x = $35.25

Putting the values of mean and SD we get,

z = \frac{35.25-27}{5.50}\\z = \frac{8.25}{5.50}\\z =1.5

The value of z-score for a price of $35.25 per barrel is 1.5

Hence,

Option 2: 1.5 is the correct answer.
