Question

Melisande collected 14 bottles on Saturday and 9 bottles on Sunday for recycling. On Monday, she took all the bottles to the recycling center, where they paid her a certain amount, b, for each bottle. However, she had to pay the recycling center a one-time service fee of $0.25. If she left there with $3.20 for the bottles, what is the value of b?

Answer 1

Answer: The value of b is $0.15.

Explanation:

Total bottles co0llected = 14+9 =23

Payment for each bottle = b

Total payment she will get = 23b

One -time service fee = $0.25

She has left = $3.20

According to the question,

23b - 0.25 = 3.20

⇒23b = 3.20+0.25

⇒23b = 3.45

⇒b = 0.15 [divide both sides by 23]

Cost of each bottle = $ 0.15

hence, the value of b is $0.15.
