Answer: the answer is 80
Step-by-step explanation: How i got this answer is i followed the PEMDAS order (parenthesis, exponent, multiplication, division, addition, subtraction)
So according to the order, i had to do the parenthesis first, (4+3.50+6+2.50)
(( what i did was i just broke the problems into 2 so it would be much more easier)) (4 + 3.50 = 7.5) and the next (6 + 2.50 = 8.5) Then you would add those numbers together (7.5 + 8.5 = 16)
We can see that we still have the 5 left over, so now all you gotta do is just multiply now. (16 x 5 = 80)
So the answer u r left off with is 80.
