Question 7 pg. 149

100 is the number of caribou moved to a new location.Then another 10% came. It then became 110. Then it increased by 20% the next year, it became 132 because it was 20% of the new number of caribou

For the show you know I'll use 400 as my price

50% off for a day

50% of 400 is basically 200 because 50% is half so you divide by 2

so the total is $200

25% off followed by another 25% off the reduced price the next day

25% of 400 equals 100 400-100=300

so now the price is 300 the first day.

25% of 300 equals 75 so 300-75 equals 225

so the total is 225.

As you can see the 50% off for a day is better than 25% followed by another 25% the next day
