given:
original cost= $45.00
discount= 20%
to find:
the sale price of the skateboard.
solution:
[tex]original \: price \times \frac{discount \%}{100} [/tex]
[tex] = 45.00 \times \frac{20}{100} [/tex]
[tex] = 45 \times 0.2[/tex]
[tex] = 9.00[/tex]
[tex]45 - 9[/tex]
[tex] = 36.00[/tex]
therefore, the sale price of the skateboard is $36.00
