Cindy purchased 100 bricks. Each brick is within 1/8 inch of the advertised length of 8 inches. Cindy will line the bricks up en
AURORKA [14]
If each brick is within 1/8 inches of 8 inches, then that's an error of
 \frac{(\frac{1}{8})}{8} =\frac{1}{64}
If we then take the total length if each brick is 8 inches,
100*8=800
Then take 1/64 of this
800*\frac{1}{64}=12.5[tex] So the upper and lower bounds are 12.5 inches either side of 800 inches 787.5, and 812.5 So we can say that [tex]787.5 \leq x \leq 812.5
Which would be the answer to part a. parts b and c would be the lower and upper bounds, so 787.5 and 812.5 respectively
Hope this helps

kumpel [21]

The selling price will be $232 if he applies a 45% markup.

Step-by-step explanation:

Cost of each stereo = $160

Mark up = 45%

Amount of mark up = \frac{45}{100}*160

Amount of mark up = \frac{7200}{100} = \$72

Selling price = Cost of stereo + mark up

Selling price = 160 + 72 = $232

The selling price will be $232 if he applies a 45% markup.
