Maybe it’s y=1x-2. I hope this helps since we have no clue what the x is in the question we just assume it’s own

Answer:
$8.50
Step-by-step explanation:
I don't know what Alls are, but if Carlos insists, we can calculate how much he can spend on Alls with the expression:
($31.50) + r  $40
 $40
This says the sum of what Carlos has already spent (hot dogs and hamburgers) plus the amount he spends on Alls (rolls?), r,  must be equal to or less than the $40 he has allowed himself to spend.
($31.50) + r  $40
 $40
r   $40 - $31.50
 $40 - $31.50
r  $8.50
 $8.50
 
        
             
        
        
        
Answer:
see below
Step-by-step explanation:
12 banana muffins, 10 chocolate muffins, 6 blueberry muffins, and 7 vanilla muffins.
The total number of muffins is 35 muffins
P(vanilla) = number of vanilla/ total
                = 7/35
                = 1/5
This is not likely to occur so it is an unlikely event
