Answer 1

Hint: In the question we are asked if Ed spent 8.5% of his savings on lunch, which costs \[\$5.35\]. How much did he have in savings before lunch. To do this question, first we have to take the savings as x since it is an unknown variable. Then we have to write the equation as \[\dfrac{8.5}{100}\times x=5.35\]. Then we have to solve this equation to get the answer for x. This x is the savings he had before lunch.

Complete step-by-step answer:
In the given question we have to find the savings Ed had before lunch if Ed spent 8.5% of his savings on lunch, which costs \[\$5.35\].
To solve this, first we have to take the savings as x since it is an unknown variable. Then we have to write the equation as \[\dfrac{8.5}{100}\times x=5.35\]. Then we have to solve this equation to get the answer for x. This x is the savings he had before lunch..

First, take savings as x and write the equation.
\[\Rightarrow \dfrac{8.5}{100}\times x=5.35\]
Then we will take the 100 to the right hand side of the equation.
\[\Rightarrow 8.5\times x=5.35\times 100=535\]
Next, we will take 8.5 to the right hand of the equation.
\[\Rightarrow x=\dfrac{535}{8.5}=62.9411765\]
Therefore, we get the final answer of the question as \[\$62.941\].

Note: In order to solve this question, you have to first write the question as an equation. You have to be careful while doing the calculations and writing the numbers. And also another important thing is the units. You have to put the units at the end of the answer.
