OpenStudy (anonymous):

Wait

OpenStudy (anonymous):

what??????????

OpenStudy (ltrout):

The answer is D. Not C

OpenStudy (anonymous):

how did you get that i need to know in case i get another problem like this one

OpenStudy (ltrout):

5n + 75q would be 160 Cents, not 1.60.

OpenStudy (anonymous):

it is not D because you have 1 dollar and 60 cents so it is 1.60

OpenStudy (anonymous):

but wouldn't that mean peggy has $1.60?

OpenStudy (ltrout):

Yes but they are saying that n is worth 5 cents, so it wouldn't be 1.60, because then 1 n would already be 5 > 1.60.

OpenStudy (ltrout):

160 cents is the same as $1.60

OpenStudy (anonymous):

but you would still have one dollar and sixty cent correct? so wouldnt it be 1.60?

OpenStudy (anonymous):

but you have $1.60

OpenStudy (anonymous):

so $1.60?

OpenStudy (ltrout):

Yes 160 Cents is still equal to $1.60.

OpenStudy (ltrout):

No, the answer is the final one 160. Not 1.60

OpenStudy (anonymous):

so c is my answer?

OpenStudy (ltrout):

D is the correct answer.

OpenStudy (anonymous):
