Answer:
90
Step-by-step explanation:
Be sure to use PEMDAS. Begin with parentheses, the move to multiplication, then adding.
20 + 3(7 + 4) + 5 + 2(7+9)
20 + 3(11) + 5 + 2(16)
20 + 33 + 5 + 32
You can add those final four numbers in any order you want, to get a sum of 90.
The answer is 7.6 so the closest estimate would be 8. 8 is the answer
