14 plums cost $2.00. what is the cost, to the nearest cent, of 50 plums?

So what you are going to do here is get the amount that is closest to 50 plums first. How many times does 14 plums goes into 50 plums? 14 plums goes into 50 plums about 3.5 times or in layman's terms 3 and a half times. Therefore, 14 plums at $2.00 a batch must be multiplied 3.5 times. So $2.00 plus $2.00 + $2.00 + $ 1.00 (Since it is only half a batch of plums)= $7.00  It is somewhere in this ball back. An even closer approximation would be calculator wise: 3.57 times $2.00 per 14 plums which is $7.14. Hopefully, this helps.

Maybe the answer is 20mm. all i really did was just multiply, which is obvious.
