Answer:
5
Step-by-step explanation:
2.63x5 = 15.78
I rounded it and the answer is 400
For the range:
5, infinity
63 + 36...there is a common factor of 9
9(7 + 4) <== this is equivalent
63 + 36...there is a common factor of 3
3(21 + 12)...but this is not an answer choice...but it is equivalent
100,000
because the 8 makes the 9 round up into a 10
