You want to start a garden. The roses cost $16 per 3 packets of seeds. How much money do you need if you want to by 8 packets of seeds? Round your answer to the nearest cent.
We know that $16 is per 3 so 3 x 3 = 9 but that is to high but it = $48 per 9 packets and scince 16 divided by 3 = 5.3 we need to take off 5.3 from 48 which makes $42.70
