Answer:
88 adult tickets and 77 student tickets were sold.
Step-by-step explanation:
Let the number of adult tickets sold be 8x and the number of student tickets sold be 7x.
adult tickets + student tickets = 165 tickets
8x + 7x = 165
15x = 165
x = 165 ÷ 15
= 11
No. of adult tickets sold (8x) = 11 × 8
= 88
No. of student tickets sold (7x) = 11 × 7
= 77
1. The first one I think you would divide 8 from 64 n get 8 so thats 8%. Answer to that would be the Store.
2. You would!! 56%
3. Multiply 2.5 to 40 and 25. You need a denominator of 100. 62.5/100
So yes you did find at least 60%
I think I did this right. Hope it helps!
