Answer:
<h2>3 ounces</h2>
Step-by-step explanation:
Step one:
given data
the initial amount of chemical = 1.25 ounces
Extra amount of chemical =2.5 ounces
Total amount of chemical =1.25+2.5=3.75 ounces
Step two:
we are told that the scientist used 0.75 ounces of chemical
Hence the remaining chemical is
remaining= 3.75-0.75
remaining= 3 ounces
<u>The remainder is 3 ounces</u>
My best answer would be (D)
-11b-4-11b-4
=-22b-8
-22b-8-b+3-b+3
=-24b-2
