Final answer:
The wholesale cost of the TV is found by solving the equation 1452 = 126 + 3w. After subtracting 126 from both sides and then dividing by 3, the wholesale cost is determined to be $442.
Step-by-step explanation:
The student is asking to find the wholesale cost of a high-definition TV. The retail selling price is given as $1452, and this is made up of $126 plus three times the wholesale cost. If w represents the wholesale cost, we can set up the equation like this:
1452 = 126 + 3w
Subtracting 126 from both sides of the equation gives us:
1452 - 126 = 3w
1326 = 3w
Next, we divide both sides by 3 to solve for w:
1326 / 3 = w
w = 442
Thus, the wholesale cost of the TV is $442.
