Final answer:
To meet the net price of $922.25, Ward must allow an additional percent discount of approximately 12.5% on the treadmill.
Step-by-step explanation:
To find the additional percent discount that Ward must allow, we can start by calculating the price of the treadmill after the initial discounts. We can calculate the first discount by finding 33 1/3% of $1860:
$1860 * (33 1/3/100) = $620.
The price of the treadmill after the first discount is $1860 - $620 = $1240.
Next, we can calculate the second discount by finding 15% of $1240:
$1240 * (15/100) = $186.
The price of the treadmill after both discounts is $1240 - $186 = $1054.
To determine the additional percent discount that Ward must allow to reach the net price of $922.25, we can subtract $922.25 from $1054:
$1054 - $922.25 = $131.75.
Finally, we can calculate the additional percent discount by finding what percent $131.75 is of $1054:
($131.75 / $1054) * 100 ≈ 12.5%.
Therefore, Ward must allow an additional percent discount of approximately 12.5% to meet the net price of $922.25.
