Ateam is selling pop corn for a fundraiser. the first week, they sell 500 bags. the second week, they sell 50% more than the first week. during the third week, they sold 50% less than the second week. what is the group’s percent decrease from the first to the third week?

The percentage decrease from the first week to the third week is 25 %

Step-by-step explanation:

The number of popcorn bags sold on the first week = 500 bags

The second week, they sell 50% more than the first week

So, the number of bags sold on the second week is

= 500 + 50% of 500

=

=

= 500 + 250

= 750 bags

The third week, they sold 50% less than the second week

So, the number of bags sold on the third week is

=  750 - 50% of 750

=

=

= 750 - 375

= 375 bags

Now the percentage decrease from the first week to the third week is

=

=

=

= 25 %
