We are given cost price of the 100 watt Solar panel price= $146.
Sale price of the 100 watt Solar panel = 0.75 of the regular price.
The regular price is same as the cost price of the solar panel.
So, we need to find the value of 0.75 of $146.
"of" word represents multiplication operation.
So,
0.75 of $146 = 0.75 * 146 = $109.50.
Therefore, the sale price of the Solar panel is $109.50.
