Five sisters bought matching scarves and two pairs of socks. The scarves were priced at $12.00. If the total bill for all 5 sisters was $125.00, what was the price of one pair of socks.

The answer is $6.50

Answer: $6.50

Justification:

Work backward step by step.

1) Total bill: $125 given

2) Value of five scarves: multiply the number of scarves time the unit price

5 * $12.00 = $ 60.00

3) Value of the socks: subtract the value of the scarves from the total bill

$ 125 - $ 60 = $65

4) divide $65 by the total number of pair of socks

If each bought two pairs, the total number of pairs is 5 * 2 = 10

So, the price of one pair is $65 / 10 = $6.50

Now, you can verify:

- two pairs of socks each sister * 5 sisters = 10 pairs

- 10 pairs of socks at $6.50 each = 10*$6.50 = $ 65

- Five scarves at $ 12 each = 5 * $12 = $ 60

- Total bill = $ 65 + $ 60 = $ 125 = > check.
