A housewife has sufficient charcoal to last 12 days provided she only uses 2 buckets of charcoal a day. How long will the charcoal last if she uses 3 buckets a day?

Respuesta :

I’m posting this again on here because the other person was incorrect, though I already answered on the other version of this question. :)

Alright, here is how you do this.

We know that if the housewife uses 2 buckets a day during the course of 12 days, that means, all in all, she used 6 buckets during those twelve days.

This means that if she uses 3 buckets a day, she will only have enough charcoal for 2 days, because 6/3 is 2.

Therefore, your final answer is 2 days

I hope this helped! Comment if you need me to explain it further or have any questions regarding it! :)

The charcoal lasts if she uses 3 buckets a day is 8 days and this can be determined by using the unitary method.

Given :

A housewife has sufficient charcoal to last 12 days provided she only uses 2 buckets of charcoal a day.

The following steps can be used to determine the number of days the charcoal last if the housewife uses it 3 buckets per day:

Step 1 - The unitary method can be used to determine the number of days the charcoal lasts if the housewife uses it 3 buckets per day.

Step 2 - Determine the total number of buckets charcoal lasts when it is used 2 buckets per day.

[tex]= 12 \times 2[/tex]

= 24 buckets

Step 3 - According to the given data, if the housewife uses charcoal 2 buckets per day then it will last 12 days. So, if the housewife uses 3 buckets per day then the number of days charcoal lasts is:

[tex]=\dfrac{24}{3}[/tex]

Step 4 - Divide 24 by 3 in the above expression.

= 8 days

So, the charcoal lasts if she uses 3 buckets a day is 8 days.
