Answer:
{x|x¥8} is the answer to the question
The number between -1 and 10 means start counting from 0 and stop just before 10. Which is 9. And only include the odd integers.
So, the set will be {1, 3, 5, 7, 9}.
EDIT:
I want to give a thank you to Helpwithschool for finding a mistake in my answer!
400 divided by 5 = 80.
Needs to bag at least 80.
Make this into an equation keeping the number as x
3x-3 = 57+x
3x-x = 57+3
2x=60
x= 30
prove this by substituting the x
30*3 -3 =57+30
87=87
there you have it :)
