Answer:
1. $548.90
2. $349.30
Step-by-step explanation:
So lets start with the 10% increase. Since its an increase we need to multiple the original price by 1.10 to add the 10% to the price
499*1.10=548.90
So the price with the 10% increase is $548.90
Now lets do the 30% decrease. Since its a decrease we need to multiply the price by .7 since that is the price after the 30% or.3 are take of from the original price.
499*.7=349.30
The price with the 30% decrease is $349.30
