Given: The watermelon costs $2.40 before a 30% discount.
To Find: An equation to find out the discounted price of the watermelon
Calculation/Explanation:
As the discount is 30%, this means a value of [tex](\frac{30}{100}).(2.40) = 0.72 $[/tex] should be deducted from the original price to find the new price after discount.
Thus, new price of the watermelon after the discount is [tex]2.40-0.72=1.68[/tex] dollars.
Thus, the expresion that denotes the new price after the discount is [tex]2.40 - ((\frac{30}{100}).(2.40)) \\=2.40-0.72\\=1.68 $[/tex]
