Let number of adult tickets be a , therefore number of student ticket be a+4 .
And total cost of the tickets is 58, that is
Distributing 2.50 on a+4
Combining like terms
Number of adult tickets are 8 and number of students tickets are 12.
Im not sure how correct this is but this is my best try, apologies for bad handwriting
Answer:

$14.98 + $2.247 = $17.227
Answer:
gloves cost $5
hats cost $4
Step-by-step explanation:
four pairs of gloves and four hats for $36.00
4g + 4h = 36
three pairs of gloves and four hats for $31.00
3g + 4h = 31
-------------------------
Subtract the second equation from the first
4g + 4h = 36
-( 3g + 4h = 31 )
––––––––––––
g = 5
gloves cost $5
substitute for g = 5 into either equation
4(5) + 4h = 36
20 + 4h = 36
Subtract 20 from both sides
4h = 16
Divide both sides by 4
h = 4
hats cost $4
If is was a property in think it would be Identity Property of Addition
