the u.s department of agriculture reported that 57 out of every 100 milk drinkers drink skim milk. if a storeowner orders 24 gal
S_A_V [24]
STEP 1:
Find percentage. 57 out of 100 is the percentage to multiply by.

57/100= 0.57 (= 57%)

STEP 2:
Multiply percentage by the total gallons ordered (24).

=24 gallons * 0.57
=13.68 gallons


ALTERNATIVE METHOD (use which works best for you)

Set up a proportion. 57 to 100 is x out of 24 gallons.

x= number skim gallons to order

57/100= x/24
cross multiply
(57*24)= (100*x)
1368= 100x
divide both sides by 100
13.68 gallons= x

ANSWER: Since you cannot order a partial gallon of milk, round up to 14 whole gallons

Hope this helps! :)

<h3>What are singular and plural pronouns?</h3>

Singular nouns, which are used to refer to a single person, place, thing, or idea, are replaced by singular pronouns.

When referring to more than one person, place, thing, or idea, plural pronouns take the place of plural nouns.

The plural pronoun "their" was used earlier in the text, but the construction "he or she" does not match that usage. Only choice D addresses existing issues without introducing new ones. The other choices are wrong because they are grammatically incorrect.
