URGENT I got an answer, but I'm really not sure if I did it right. The answer I got from my calculator was 11.202 but I'm not sure if I typed in the equation right, or even if my calculator is in the right mode. I'm testing my trig skills quickly now right before a big maths exam I have today, so asap answers are much appreciated!!!

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.
