Pls pls pls answer 5 and 6 and tell me the correct answer and how to get the correct answer . whoever answer this correctly i will give them 26 points pls me i need the answer

The answer to 5 is A. And the answer to #6 is B. Here is why: So the cost for 6 pens is $2.34. So, you want to find the unit rate. The unit rate basically, in this case, would be how much on pen costs. So to find how much one pen costs you would divide 6 into $2.34. That would give you .39¢. Now to find out how much 20 pencils would cost you would multiply .39¢ by 20. This would give you $7.80. Do you see it now? I hope this could be helpful!

The first answer is A because to find the unit price, you would have to divide 2.34 by 6 and then multiply the quotient by 20.
The second is B because when you follow the steps in A, 2.34/6= 0.39 and 0.39x20= $7.80
