(02.01 lc)
while researching the industry she is interested in, fernanda sees that the average unemployment rate is 4.3%. how many people, out of every 315, are unemployed? round the final answer to the nearest hundredth.
13.55
25.12
47.23
73.26

Explanation:

Step1: Convert percentage to decimal

The unemployment rate is \(4.3\%\). To convert a percentage to a decimal, we divide by \(100\). So \(4.3\%=\frac{4.3}{100}=0.043\).

Step2: Calculate the number of unemployed people

We want to find out how many people out of \(n = 315\) are unemployed. We use the formula \(x=n\times r\), where \(r\) is the unemployment - rate (in decimal form). Substitute \(n = 315\) and \(r=0.043\) into the formula: \(x = 315\times0.043\).

Step3: Round to the nearest hundredth

Rounding \(13.545\) to the nearest hundredth. The digit in the thousandth place is \(5\). Using the rounding rule (if the digit in the thousandth place is \(5\) or greater, we round up the digit in the hundredth place). So \(13.545\approx13.55\).

Answer:

13.55
