7</h2><h3>Consider how many times 30 goes into 210(exactly 7 times) and that will be your answer.</h3>
4d = 24 would be the right equation. To double check you would divide both sides by 4 (the number of legs) to find the amount of dogs.
Paul needs to invest $10000 at 6% interest and $30000 at 10% interest to make a total of 9% return on his $40000.
