Aveeno and her boyfriend you know who wrote the bus six times in a month it cost $40 for the two of them each time if Avena alwa
MaRussiya [10]

Answer: The cost for the month is $240.

Step-by-step explanation:

Since we have given that

Cost for the two i.e Aveeno and her boyfriend = $40

They were charged 6 times in a month.

As we know that times stands for multiplication.

So, we need to find the cost for the month, where we multiply 6 with $40 to get the amount for the whole month.

So, the amount for the month would be

40\times 6=\$240

Hence, the cost for the month is $240.
