Answer:
$2,500
Step-by-step explanation:
Method 1:
[tex]\begin{array}{cccc}5\%&-&\$125&\text{multiply both sides by 20}\\\\100\%&-&\$2,500\end{array}[/tex]
Method 2:
[tex]\begin{array}{ccc}5\%&-&\$125\\\\100\%&-&\$x\end{array}\qquad\text{cross multiply}\\\\\\5x=(125)(100)\qquad\text{divide both sides by 5}\\\\x=\dfrac{(125)(100)}{5}\\\\x=(125)(20)\\\\x=2,500[/tex]
Method 3:
[tex]p\%=\dfrac{p}{100}\\\\5\%=\dfrac{5}{100}=\dfrac{1}{20}\\\\5\%\ of\ x\ is\ \$125:\\\\\dfrac{1}{20}\cdot x=125\qquad\text{multiply both sides by 20}\\\\x=2,500[/tex]
