AVprozaik [17]

Answer:

  16^25

Step-by-step explanation:

Melisande collected 14 bottles on Saturday and 9 bottles on Sunday for recycling. On Monday, she took all the bottles to the rec
Ann [662]

Answer:

Option B is correct that is  amount she is getting per bottle is $0.15  

Step-by-step explanation:

We have been given the information that melisande collected 14 bottles on saturday and 9 bottles on sunday

That means she has collected total of 23 bottles

Let us assume that the amount she is paid for recycling is $b

Since, she is left with $3.20 after the amount she gets for bottles we will get the equation below:

23b=3.20

Now, since she has to pay one time service fee equation will become

23b -0.25 =3.20

After simplification we will  get

23b=3.20+0.25=3.45

b=3.45/23=.15

b=$0.15

Therefore, The amount she is getting per bottle is $0.15
