In the 1990s, the number of target stores increased from 420 stores to 914 stores. What was the percent increased in the number
tino4ka555 [31]
Divide 914/420, move the decimal over to the right two places and you'll get approximately 217.5%

EDIT: My mistake, read question wrong.
914-420 = 494
494/420 = 1.17
<u></u>117.62% 
Subtract the difference and divide by original number (: Move decimal place over two places.

Solve for the indicated variable
GrogVix [38]

Answer:

X_1=\frac{YX_2}{X_2-Y} \\\\

Step-by-step explanation:

\frac{1}{Y}=\frac{1}{X_1}+\frac{1}{X_2}

First subtract the 1/x2

\frac{1}{Y} - \frac{1}{X_2}=\frac{1}{X_1}

Next subtract the fractions on the left

\frac{X_2-Y}{YX_2}=\frac{1}{X_1}\\

Next Multiply by x1

\frac{(X_1)X_2-Y}{YX_2}=1\\

Next divide both sides by the remaining parts (not x1)

X_1=\frac{YX_2}{X_2-Y} \\\\
