Answer: Andres
Explanation:
y = goals made
x = goals attempted
For Andres, his ratio is y/x = 4/8 = 1/2 = 0.50 meaning that he made 50% of his attempts
For Deyvi, the ratio is y/x = 9/20 = 0.45 = 45%
Andres has the better record.

Answer:
Number of student tickets were sold = 409
Step-by-step explanation:
Total number of tickets sold = 771 
I.e Students ticket (S) + Non students ticket(N S)  = 771
Total amount to be paid for tickets = $ 3037
Amount paid by students per tickets = $3
Amount paid by non-students per tickets = $5
So, according to question
S + NS = 771
3 S + 5 NS = 3037
Solve both equations  
5 S + 5 NS = 771 × 5
3 S + 5 NS = 3037
so ,
(5 S + 5 NS) - (3 S + 5 NS ) = 3855 - 3037
Or, 2 S = 818
I.e S =  = 409
 = 409
Hence, The number of student tickets were sold = 409      Answer
