If the builder has $187 and if each box of nails cost $4 then she can buy 46 complete boxes.
Given: Money the builder has = $187
Cost of each box of nails = $4
If an item costs x amount and a person has y amount, then how to calculate how many items can be bought?
Cost of item = x
Amount the person has = y
So it costs x amount for 1 item.
Then it costs 1 unit amount for 1 / x item.
Y unit amount will cost, multiplying the above line with y.
Therefore it costs y amount for y / x item.
Hence with y amount the person can buy y / x number of items when each unit item cost x amount. [ We are following simple unitary method approach ]
What is unitary method?
Unitary method is a process in which we find the value of an unit amount from a given information and then we multiply the value of the unit amount to the required number for the solution.
Now let's solve the problem:
Given that, Builder has $187
Cost of each box of nails is $4
So, 1 box costs $4.
Then with $1 will buy 1 / 4 box.
so $187 will buy , multiplying the above line with 187
$187 will buy 187 / 4 boxes.
$187 will buy 46.75 boxes.
Now, no information is given that if a part of a box is sold or not. So we will not consider the fractional part and approach the question with the believe that, only a whole single unit is sold.
Therefore $187 will buy 46 boxes.
Hence if the builder has $187 and if each box of nails cost $4 then she can buy 46 complete boxes.
