The manager of a restaurant offers a 20% decrease in price to tennis teams. A cashier applies a 10% decrease and then another 10% decrease. Is this the same as applying a 20% decrease

Respuesta :

Answer: No

Step-by-step explanation:

20% decrease in price refers to the

[tex](1-20\%)=(1-0.2)=0.8[/tex]

i.e. 0.8 times the original price

while a successive decrease of 10% refers to

[tex](1-10\%)(1-10\%)=(1-0.1)(1-0.1)=0.9\times0.9=0.81[/tex]

0.81 times of original price

So, a 20% discount is a bigger discount than two 10% discounts
