Answer: 160
Step-by-step explanation:
So here they are telling you that there are 4 twelves, a.k.a 4 groups of 12. Which means that you have to multiply 4 x 12 = 48
Then there are 7 sixteens, a.k.a 7 groups of 16.
Which also means that you have to multiply 7 x 16 = 112
Add both numbers and there you have your answer!
