Question 1205528
<br>
The number of footballs is 4 more than a multiple of 7 and also 4 more than a multiple of 5.  Since 5 and 7 are relatively prime, the number of footballs is 4 more than a multiple of 7*5=35.<br>
The smallest number that is 4 more than a multiple of 35 is 35(1)+4 = 35+4=39.<br>
That of course does not consider the absurd case where the number of footballs is 35(0)+4 = 4.<br>
ANSWER: 39<br>
