Bob has three times as many baseball cards as Bill. Together they have a total of 68 cards. How many cards does Bob have?

OpenStudy (anonymous):

Cards of bill *cards of bob=68

OpenStudy (anonymous):

Bob has x cards. Bill has 3 times bobs cards.

OpenStudy (anonymous):

so how would you make this equation?

OpenStudy (anonymous):

i wish i knew

OpenStudy (anonymous):

Try :P .

OpenStudy (anonymous):

3x=68?

OpenStudy (anonymous):

i know that isnt right

OpenStudy (anonymous):

good job!!!

OpenStudy (anonymous):

wait it was right?

OpenStudy (anonymous):

Yes! :D .

OpenStudy (anonymous):

But that's really strange because you have a decimal number of cards and I would expect ti to be a whole number.

OpenStudy (anonymous):

it*

OpenStudy (anonymous):

I thought it would be x+3x=68

OpenStudy (anonymous):

Are you SURE it was 68 cards and not 69?

OpenStudy (anonymous):

Why? @CalebBeavers

OpenStudy (anonymous):

Wait.

OpenStudy (anonymous):

Caleb is correct.

OpenStudy (anonymous):

x=bills cards 3x=bobs cards add them you get 68

OpenStudy (anonymous):

Because the sum of their cards is 68.

OpenStudy (anonymous):

then would the answer be 17?

OpenStudy (anonymous):

yes.

OpenStudy (anonymous):

How could I get his wrong!?!?!? :( .

OpenStudy (anonymous):

sweet

OpenStudy (anonymous):

x was bills cards. you want how many bob had, which is 3 times bills

OpenStudy (anonymous):

I know I know... Sigh... I had a dumb moment.

OpenStudy (anonymous):

so bob has 51.
