Answer:
$22
Step-by-step 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
![\$32+\$14+x](https://img.qammunity.org/2023/formulas/mathematics/college/jgm60c932gl7czn39ujwbl8a3ngg85ns8w.png)
We are told that the total cost is $68, which means
![\$32+\$14+x=\$68](https://img.qammunity.org/2023/formulas/mathematics/college/5o4pzfubpf4xyamokvkj59fa6h9akyfuyu.png)
SInce 32 + 14 = 46, the above becomes
![\$46+x=\$68](https://img.qammunity.org/2023/formulas/mathematics/college/h6y54gdgn1f10ax3edxb09415nxh9yvdhl.png)
subtracting 46 from both sides gives
![x=\$68-\$46](https://img.qammunity.org/2023/formulas/mathematics/college/41celq248k4dk5ndnptq7cgbpq2iifc056.png)
![\boxed{x=\$22.}](https://img.qammunity.org/2023/formulas/mathematics/college/3pmsz1iyn0d9i01sf8nno0vvvbfnlr9rx4.png)
Hence, the price of the jeans is $22.
