WILL GIVE BRAINLIEST A chess rook on the leftmost cell of a 1x30 lane and can move any number of cells, but only to the right. In how many ways can the rook move to the rightmost cell?

If i think this is what your asking, he should look at the grams or pounds/ounces and compare the to their cost then max can identify which one is proportional and which is not ( i think xd)
