Answer:
This question is very tricky but i think i got it right. so first i tried making all the s's into sevens but that didn't work since it just adds up to a lower value. So i tried looking at it from another angle. This time i added the e's together to make 9 i forgot what were the e's but the fraction i came up with just didn't add up. Then i read the question again it said i cant add from 0-9 i thought i could only add from 0-5 this changed everything. I tried again and i came up with my final answer: (estimation) 250???
