Tina bought two pairs of regular socks and one pair of long fleece socks. The fleece socks cost $12. If the final price, including 5% sales tax, was 30.45, what was the price of each pair of regular socks?.

write an equation for the purchase :

$12 + 2x + tax = $30.45

(12 +2x)* 1.05 = 30.45

solve for x to get

x = $8.5

the price of a pair of regular socks is $8.50
