An equation for the opposite of 2
So the question wants you to add all the coins together then subtract 15% SO
16+28+32+4=80
so 15% of 10=10%+5%
5%=1/2 of 10% so
10% of 80=8
5% of 80=10%/2=8/2=4
8+4=12
he sold 12 coins
The answer to your question 29 is E 935,00. The way how I got this answer by multiplying 55 and 17,000 and by that the is E. For question 30 the answer is H. The way how I got this answer is by knowing twice means 2 times so by that H was the only one with 15+2n so by that I knew that was the answer.
Hope this helps:)
