Answer:
$22
Explanation;
Mark bought four hats that each cost $8. This means he spent a total of $8 *4 = $32 on hats.
Mark also bought a shirt worth $14 and a pair of jeans. We are not told what the price of jeans is and so we call it X for a moment.
Adding up all the costs, we get
[tex]\$32+\$14+x[/tex]We are told that the total cost is $68, which means
[tex]\$32+\$14+x=\$68[/tex]SInce 32 + 14 = 46, the above becomes
[tex]\$46+x=\$68[/tex]subtracting 46 from both sides gives
[tex]x=\$68-\$46[/tex][tex]\boxed{x=\$22.}[/tex]Hence, the price of the jeans is $22.
