Question

I need help answering

Answer 1

12(6) + 30(3)
= 72 + 90
= 162

Answer 2

So what you want to do is plug in the 6 for the h because it is the numbers of hours and 3 for the w because that is the number of wagons sold. When you do that it should look like this: 12x(6)+30x(3) Then use PEMDAS to solve. it should look like this: (12x6)+ (30x3)

So you multiply 12 times 6 and get 72 then multiply 30 times 3 and get 90.

Then you add 72 to 90.

Answer is 162

Let me know if that isnt right.
