Question

Last year Collin's salary was $45,000. Because of furlough days, this year his salary was $30,000. Find the percent decrease.Round to the the nearest tenth of a percent

Answer 1

33.3%

Explanation:

We can calculate the value of the percentage starting from the following equation:

`45000-x\cdot45000=30000`

We solve for x:

`\begin{gathered} -x\cdot45000=30000-45000 \\ x=(15000)/(45000) \\ x=(1)/(3)=0.333 \\ \text{ in the percent form:} \\ 0.333=33.3\text{\%} \end{gathered}`

The percentage that decreased was 33.3%
