How much of a spice that is 30% salt should be added to 175 ounces of a spice that is 65% salt in order to make a spice that is
klasskru [66]
\bf \begin{array}{lccclll}
&amount&concentration&
\begin{array}{llll}

amount
\end{array}\\
&-----&-------&-------\\
\textit{30\% spice}&x&0.30&0.30x\\
\textit{65\% spice}&175&0.65&(175)(0.65)\\
-----&-----&-------&-------\\
mixture&x+175&0.50&(x+175)(0.50)
\end{array}

so.. as you can see, we use the decimal notation for the percentages... 65% is just 65/100 and 50% is just 50/100 and so on

so.. whatever the salted amounts are, we know they'll add up to (x+175)(0.50)

thus  (0.30x) + (175)(0.65) = (x+175)(0.50)

solve for "x"

In a bid to determine the number of students that voted eagle in the election, we would simply multiply total votes of 536 by 1/3

votes for eagle=1/3*586

votes for eagle=195 votes

We have rounded to the nearest whole number since number of votes cannot be fractional
