What is the fewest number of 7's that can be added together to make their sum greater than 4000?
A) 4001
B) 572
C) 571
D) 470
7 x > 4000
x > 4000/7 or 571.4
571*7 = 3997 too small
572*7 = 4004, that will do
so
572
To find the fewest number of 7's that can be added together to make their sum greater than 4000, we start by dividing 4000 by 7.
4000 ÷ 7 = 571 remainder 3
This means that we can add 571 sevens together to get a sum of 3997 (571 * 7 = 3997).
However, we want the sum to be greater than 4000, so we need to add one more 7.
Thus, the fewest number of 7's that can be added together to make their sum greater than 4000 is:
571 + 1 = 572
Therefore, the answer is option B) 572.
To determine the fewest number of 7's that can be added together to make their sum greater than 4000, we need to find the smallest value that exceeds 4000 when multiplied by 7. We can start by dividing 4000 by 7 and rounding up to the nearest whole number.
4000 / 7 = 571.42857
Rounding up, we get 572.
Therefore, the fewest number of 7's that can be added together to make their sum greater than 4000 is 572.
So the correct answer is option B) 572.
