First, subtarct the stationery and the skateboard from 98

OpenStudy (anonymous):

34 @sawq

OpenStudy (sawq):

thats the skateboard from 98 with the stationary subtracted, it 23,15

OpenStudy (anonymous):

Ok

OpenStudy (sawq):

you know 1.65 is the cost per cookie therfore you have to find out how many times 1,65 goes into 23,15

OpenStudy (anonymous):

so you would do 23,15 divided by 1,65?

OpenStudy (sawq):

yup

OpenStudy (anonymous):

Ok and that would be my answer?

OpenStudy (sawq):

yes

OpenStudy (anonymous):

Ok Thank you!
