Answer:
572 7s are needed to be added together
Step-by-step explanation:
Basically, what we are asked here is the multiple of 7 which is closest to but above 4,000
Then, from this multiple , the number of 7s which are added together to give it is our answer.
By multiplication; 7 * 572 = 4,004
This is the closest multiple of 7 to 4000 which is also above it.
So the fewest number of 7s which we can add together is 572
