Answ

$11.00

Step-by-step explanation:

A quick way to do this would be as follows: 1.10 ( 0.50*$20), or $11.00.

0.50($20) gives us the sale price (at half off); that's half of $20, or $10.

The total due is then $10 (item cost) plus $1 (tax), or $11

a laboratory technician needs to make a 40-liter batch of a 40% acid solution. How can the laboratory technician combine a batch

Anettt [7]

The answers comes to be for every 1 unit of pure acid (100%) add three units of 20% and you get the desired 40%

so if you need 40 L (i don't know what container sizes there are so i can't give you an exact amount just add 1 part 100% acid and 3 parts 20% acid) <span />
