Step-by-step explanation:

100% = X

50% = 100%/2 = X/2

X decreased by 50 means X - 50% = X - X/2 = X/2

now,

100% = X/2

50% = 100%/2 = X/2 / 2 = X/(2×2) = X/4

increasing the previous result by 50% means

X/2 + 50% = X/2 + X/4 = 2X/4 + X/4 = 3X/4

so, comparing this to the original X (= 4X/4), we are X/4 short.

2 boxes for $6.00 5 Bars each is 10 bars for $6.00 or $3.00 for 5 bars

12 bars for $7.44 is $7.44 divided by 12 =.62 or 62 cents per bar

so the difference between 60 cents and 62 cents is

katovenus [111]

$5r^2 = 80 \ \ /:5\\ \\r^2=\frac{80}{5}\\ \\r^2=16\\ \\r^2-16=0\\ \\ r^2 - 4^2 =0 \\ \\(r-4)(r+4)=0$

$r-4=0 \ \ \vee \ \ r+4 =0 \\ \\r=4 \ \ \vee \ \ r = -4 \\ \\ \\ a^2-b^2 = (a- b)(a+b)$
