Problema Solution

Mrs.Smith bought 4 lbs of meat with 2/5 of her money. she still had $24 left. How much did 1 lb of meat cost?

Let 'x' represent the cost of 1 lb meat, x>=0.

Since 2/5 of the money was spent on mean what is left is 3/5 of the money and that equals $24.

If 3/5 is $24 than 1/5 is 24/3 = $8 thus 2/5 of the money equals 2*$8 = $16. Now we can write:

4x = 16 (4x is the total cost of 4 lbs of meat)

........

........

x = $4 per lbs

1 lb of meat costs $4.
