OpenStudy (acxbox22):

is this a test?

OpenStudy (briellshaw):

No.

OpenStudy (briellshaw):

I had got kicked out of homeschooling its a long story but i just got back in two weeks ago and im doin extra credit work to bring my grades up

OpenStudy (acxbox22):

alright, hint: 1 gallon costs 3.15 and you need 20 gallons so which statement matches that?

OpenStudy (briellshaw):

oh so 20*3.15=63

OpenStudy (acxbox22):

exactly how else can you represent 20 x 3.15?

OpenStudy (briellshaw):

put it in 20 groups??

OpenStudy (anonymous):

3.15+3.15+3.15+3.15+3.15+3.15+3.15+3.15+3.15+3.15+3.15+3.15+3.15+3.15+3.15+3.15+3.15+3.15+3.15+3.15

OpenStudy (acxbox22):

for example: 2 x 5 = 2+2+2+2+2 right? so the same goes for 3.15 x 20 pretty much like @OrangeMaster said

OpenStudy (briellshaw):

so do i put it in 20 groups which means B. is the answer

OpenStudy (texaschic101):

no

OpenStudy (acxbox22):

if we put 3.15 into 20 groups we would divide 3.15 by 20

OpenStudy (anonymous):

Dividing is lessening the number, and we are looking to build the number.

OpenStudy (acxbox22):

what option adds 3.15 20 times?

OpenStudy (briellshaw):

0.1575

OpenStudy (texaschic101):

example : 1 gal = 3.15 2 gal = 3.15 + 3.15 3 gal = 3.15 + 3.15 + 3.15 and so on does that help ?

OpenStudy (briellshaw):

OH C. is the answer

OpenStudy (acxbox22):

yes, good job because 15 cents doesn't sound like a realistic cost for 20 gallons of gas

OpenStudy (briellshaw):

okay thank you all
