I can help! Do you have an example problem that I can show you step by step?
I think its D. $1,800 because 10.4 multiplied by twelve is 124.8 and if you multiply that by 15 you get $1.872.
If you divide 12.5 by 25 you should get 0.5
correct answer should be 0.5
You times 4 by everything inside the parentheses, so the answer would be as follows. 16a + 20b - 12
