2(6.75)+1.03+3S=22 therefore 3S = 14.53 divide by 3 so S equals 4.84 per pair of socks

each pair of socks cost $2.49

Step-by-step explanation:

Eric spent $22.00, including sales tax on 2 jerseys and 3 pairs of socks. The jerseys cost $6.75 each and the total sales tax was $1.03. How much did each pair of socks cost?

Solution:

The total money spent was $22.00. 2 jerseys costing $6.75 each was bought, the total tax was $1.03. 3 pairs of socks was bought, Let S represent the cost for each pair of socks. The total money spent is the sum of the money spent on jersey, socks and tax. Hence:

2(6.75) + 3S + 1.03 = 22

13.5 + 3S + 1.03 = 22

14.53 + 3S = 22

3S = 22 - 14.53

3S = 7.47

S = 2.49

Hence each pair of socks cost $2.49
