Lisa and her daughter weigh 185 pounds all together. The ratio of lisa’s weight to her daughter weight is 4:1 . How much does li
zzz [600]

Since the ratio of mother to daughter is 4:1, the weight of the mother and daughter together is five times the weight of the daughter.

In fact, if the daughter weights d pound, the mother weights 4d pounds, and the total weight is d+4d = 5d.

We know that this total is 185 pounds, so we have

5d = 185 \iff d = \dfrac{185}{5} = 37

So, the daughter weights 37 pounds.
