How do i solve this i am having trouble

For this answer you will have to use the order of operations, aka PEMDAS.
P-Parenthesis
E-Exponents
M-Multiplication
D-Division
A-Addition
S-Subtraction

This is a very easy question because there aren't any exponents.

We can first look at the Parenthesis because that is what comes first in PEMDAS.

(17+5) All we have to do is 17+5= 22

Then we can do multiplication...

so we have 22 times .5 which equals 11.

Lastly, we will do subtraction because there is no addition

50-11= 39

Our answer will be 39.

I think it is 1,039
All you have do is, 17+5=22 and then you put that to the side for now an do 50-0.5 which is 49.5then multiply 49.5 by 22 and that gives you 1,039.
I hope this helps.
