Question

Juan buys 4 shirts on sale for $15 each. He also buys 6 pairs of socks, each pair of socks being the same price. If the total cost for the clothes is $78, how much did one pair of socks cost?. A.. . $3. B.. . $8. C.. . $3.70. D.. . $3.50

Answer 1

$3 for each pair of socks

Answer 2

The total cost for the clothes is the sum of the total cost for the shirts and that of the socks. Let x be the price of each sock and that the equation that would best represent the given above is,
4(15) + 6x = 78
The value of x is 3. Therefore, each sock costs $3.
