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?
