A. 7/3*s B. 10/3*s C. 7/2*s D. 4s E. 9/2*s oh, the wording is kind of confusing...s for john, then we have Sheila, which forces us to use different letter and confuse us a little bit... so...John has S sheila has 3 times as many as john, thus 3S James has half of what has John..so 0.5S total: 3+1+0.5S or 4.5S this is equal to 9/2 S E

Usually, you will get enough data to stick to a single variable.

john = s shiela = 1/3(shiela) = s => 3s james = 2(james) =s => (1/2)s total = s+3s+(1/2)s = (9/2)s
