Question

What percentage is $150.00 of $3,436

Answer 1

To solve this problem, use the rule of three:

3,436 - 100%

150 - x

Where x is the unknown value:

Since the values are proportional:

`(3436)/(100)=(150)/(x)`

Multiplying both sides by 100x:

`\begin{gathered} (3436\cdot100\cdot x)/(100)=(150\cdot100\cdot x)/(x) \\ 3436x=15000 \end{gathered}`

And dividing both sides by 3,436:

`\begin{gathered} (3436)/(3436)x=(15000)/(3436) \\ x=4.4 \end{gathered}`

Answer: 4.4%.
