Question

What is x? 828.75=x+(x*2.1*5)/(100)

Answer 1

Answer:

$828.75=\frac{x+\left(x\cdot \:2.1\cdot \:5\right)}{\left(100\right)}$

Multiply both sides by 1150

$\frac{1150\left(x+x\cdot \:2.1\cdot \:5\right)}{100}=828.75\cdot \:1150$

$132.25x=953062.5$

Now Divide both sides by 132.25

$\frac{132.25x}{132.25}=\frac{953062.5}{132.25}$

$x=7206.52173$
