A company makes Poppy Lapel Pins. Each of them costs £1.30 to make.
In October it made 800 lapel pins.
25% of them are given to charities.
The rest are sold in two formats: 70% of them at £2.50 each
30% of them at £5.00 for 3
Assuming that all the lapel pins will be sold by the end of November,
work out the percentage profit the company should make.
Give your answer to 1 decimal place.

Please someone help it may have been answered before but it's hard to change the values at a certain stage. Thanks​

Write the percent as a fraction or mixed number in simplest form. 0.8%

The survey of study habits and attitudes (ssha) is a psychological test that measures the motivation, attitude toward school, and study habits of students, scores range from 0 to 200. the mean score for u. s. college students is about 115, and the standard deviation is about 30. a teacher who suspects that older students have better attitudes toward school gives the ssha to 55 students who are at least 30 years of age. the mean score is 113.2. assume the population standard deviation is 30 for older students what is the margin of error for a 95% confidence interval for the population mean score for a. older students? b. compute the 95% confidence interval for the population mean score for older students. c. compute the 99% confidence interval for the population mean score for older students. d. compute the 88% confidence interval for the population mean score for older students.
