How Many Dogs Did the Pet Store Sell in March?

[QUOTE="nycmathdad, post: 6784519, member: 723026"] A certain pet store sells only dogs and cats. In March, the store sold twice as many dogs as cats. In April, the store sold twice the number of dogs that it sold in March, and three times the number of cats that it sold in March. If the total number of pets the store sold in March and April combined was 500, how many dogs did the store sell in March? Let me see. Note: twice as many dogs as cats in March: Dogs = 2x Cats = x In April: Dogs = 2(2x) + 3x Total number of pets sold = 500 Here is my equation: 2x + x + 2(2x) + 3x = 500 10x = 500 x = 500/10 x = 50 In March, the store sold twice as many dogs as cats. Here, x represents the number of cats. Twice that amount is 100. I say the number of dogs sold in March is 100. You say? [/QUOTE]
