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
We are told that the total cost is $68, which means
SInce 32 + 14 = 46, the above becomes
subtracting 46 from both sides gives
Hence, the price of the jeans is $22.
