Answer:
23400 x 8/100 = 1872 = the loss

156/1872*100% = 8.33 % then round it
Can I get your number and I will help you
It's 11040 plants because 92 percent of 12000 is 11040. (Idk if this is the best reasoning but :/)
one paper sheet = 500 / 305 cents
134 * 13 = 1742
500 / 305 = 1.64 cents
1.64 * 1742 = $28.55
