Answer: $379.69
Explanation:
So first we can represent 75% as 3/4 which is easier for me to explain. so first I would do 1200*3/4 which will be 900 then I would do it again until the 5th night so 900*3/4=675 then 675*3/4=506.25 and then 506.25*3/4=379.6875. So Kaylee would sell $379.6875 but we can't do thousandths place so we round to the nearest hundredth so the final answer is
$379.69
