Answer:
4 pairs.
Step-by-step explanation:
Shin guards-$8.58
7 pairs of socks-$4.29
Pays-$25.74
Let's express following equation:
[tex]$25.74=8.58+4.29x[/tex]
x will be the pairs of socks.
[tex]25.74-8.58=4.29x[/tex]
[tex]x= 17.16{}/ 4.29{}{}[/tex]
[tex]x=4[/tex]
SO she bought 4 pairs of socks.
Hope this helps :)
