Answer:
$ 980
Explanation:
Discount for morning session = 25 % of 28 = 0.25 * 28 = $ 7
Fees for morning class = 28 - 7 = $ 21
Maximum people in one session = 10
Money earned in the morning sessions = 2 * 21 * 10 = $ 420
Money earned in the evening sessions = 2 * 28 * 10 = $ 560
Total money earned that day = 420 + 560 = $ 980
