Answer:
20.864
Explanation:
So first you have to multiply 8.15 and 4 together, and that would give you 32.6. After you multiply you got to divide, so 32.6 divided by 5 which would be 6.52. After you do all the numbers in the parenthesis you have to do the rest of the steps, which would be multiplying 3.2 by 6.52=20.864.
