Answer:
10 pairs for $13.48 is a better buy
Step-by-step explanation:
Given:
6 Pairs of socks have price $8.99
Let it call trade A
10 Pairs of socks have price $13.48
Let it call trade B
To Find:
Best buy = ?
Reason for it
Solution:
To find the best buy from both of these two trades we have to see that in which we will be charged less for per pair of socks
For Trade A:
6 Pairs of socks have price $8.99
Price of one pair of socks = Total price / Total Pairs
= $ 8.99 / 6
=$1.498 per pair
For Trade B:
10 Pairs of socks have price $13.48
Price of one pair of socks = Total price / Total Pairs
= $ 13.48 / 10
=$1.348 per pair
Trade B which is 10 Pairs of socks have price $13.48 is a better buy because of the reason that Price of per pair in Trade B is $1.348 per pair which is smaller then the price of Trade A which has a price of $1.498 per pair. So in the second case he will be saving more and per pair price is also low.
