To find the answer, we can first find the total number divisible by 7 of 50 and 500 separately:

50÷7 = 7.14...

there are 7 divisible for 50.

500÷7= 71.42...

there are 71 divisible for 500.

We can then deduct the number of divisible for 50 from 500 to find the answer:

71-7

=64

Therefore, the answer is 64.

Hope it helps!
