Question

If u want 100 points there you go. I need help. : Write an equation to help you find the value of each variable. Solve the equation. :

38% of e is 190

Answer 1

`\huge\boxed{38\%\text{ of 500 is 190}}`

Explanation:

`\bold{METHOD\ 1:}`

`\begin{array}{ccc}e&-&100\%\\190&-&38\%\end{array}\qquad\text{cross multiply}\\\\(38)(e)=(190)(100)\\\\38e=19000\qquad\text{divide both sides by 38}\\\\(38e)/(38)=(19000)/(38)\\\\e=500`

`\bold{METHOD\ 2}`

`\text{convert a percent to decimal}\\\\p\%=(p)/(100)\to38\%=(38)/(100)=0.38\\\\38\%\ \text{of}\ \bold{e}\ \text{is}\ 190\to0.38\bold{e}=190\qquad\text{divide both sides by 0.38}\\\\\\\frac{0.38\bold{e}}{0.38}=(190)/(0.38)\\\\\bold{e}=500`

Answer 2

Rewrite 38% as a decimal 0.38

Now write an equation:

0.38e = 190

Solve for e by dividing both sides by 0.38

E = 190/0.38

E = 500
