    If Sardi's d dogs eat food at a total rate of c cans each week,

    then how many cans of food would s dogs eat in x weeks

    at the same average rate per dog,

    in terms of c, d, w, and x?

    If d dogs eat c cans in a week, then c/d is amount of cans eaten in a week per dog.

    If there are x dogs, they would eat x*c/d cans in a week and w*x*c/d cans in w weeks

    Btw I also put my D in ur mom's A

    Update: Because if there are c cans that get consumed by d dogs, d dogs get c/d cans. d*(c/d)=c = total amount of cans. Example: 2 dogs eat 6 cans of food a week, then one dog eats 6/2=3 cans that week. And c/d is then the rate of food a dog eats per week. And x dogs eat a total of x*(c/d), amount of dogs x food per dog, for a given week, then if it is w weeks, we get w*x*(c/d)

      Why is the second part divided by d?

    [ ( c cans / week ) / ( d dog ) ] * ( w weeks ) * ( r dogs ) 

    = ( cwr / d ) cans
