Answer: 55% decrease

% decrease is calculated by = [ (New Value - Old Value) / Old Value × 100

63 - 140 = -77

-77/140 = -0.55

- 0.55 x 100

= -55%

Answer:

55% decrease

Step-by-step explanation:

To find the percent decrease

Take the original price and subtract the new price

140-63 =77

Divide by the original price

77/140

.55

Multiply by 100 to get the percent

.55*100 = 55%

55% decrease since the price got lower

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]

$\bf \begin{array}{lccclll}
&amount&concentration&
\begin{array}{llll}
concentrated\\
amount
\end{array}\\
&-----&-------&-------\\
\textit{30\% spice}&x&0.30&0.30x\\
\textit{65\% spice}&175&0.65&(175)(0.65)\\
-----&-----&-------&-------\\
mixture&x+175&0.50&(x+175)(0.50)
\end{array}$

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"
