Answer:
$71
Step-by-step explanation:
To calculate the cost of the ladder after the discount, first we need to find the discount price.
Discount can be calculated by using the formula;
[tex]\sf Discount = \dfrac{Discount \%}{100} \times original \ price .[/tex]
Substituting the required values, we have;
[tex]\sf Discount = \dfrac{20 \%}{100} \times \$88.75[/tex]
[tex]\sf Discount = 0.2 \times \$88.75[/tex]
[tex]\sf Discount = \$ 17.75[/tex]
Now, Cost of ladder after the discount = Original price - discount
[tex] \sf = \$88.75 - \$ 17.75[/tex]
[tex] \bf= \$71 [/tex]
Hence, the cost of the ladder after the discount is $71
