Answer: Â A. 50% Â B. 25%
Step-by-step explanation:
Given: A tennis racquet that regularly sells for $50 is on sale for $40.
Decrease in price = $ (50-40)= $ 10
Percent decrease in price of racquet = [tex]\dfrac{\text{Decrease in price}}{\text{Regular selling price}}\times100\%[/tex]
[tex]=\dfrac{10}{50}\times100\%=50\%[/tex]
The percent decrease in price on the tennis racquet = 50%.
The same store has a popular camping tent that was selling for $160 and now is marked up to $200.
Increase in price = $ 200-160= $40
Percent increase = [tex]\dfrac{40}{160}\times100\%[/tex]
[tex]=\dfrac{100\%}{4}=25\%[/tex]
hence, the percent increase in price on the camping tent = 25%
