at a pet shop there were 10 more dogs than cats, the shop sold 2 dogs and bought 2 cats, now there are twice as many dogs than cats, how many cats does the shop have now?
my answer is at first there must be 22 dogs and 8 cats so 22 dogs minus 2 dogs is equals 20 dogs and 8 cats plus 2 is equals to ten so now there are 20 dogs and 10 cats
