Answer:
Area of walkway = 16(x+4) 
Step-by-step explanation:
Length of the sides of the square outdoor = x feet
Area of the square outdoor = length x length
= x * x
=

The square outdoor is surrounded by 4 feet of walkway. So that,
length of the walkway = (x + 2(4))
= (x + 8)
Area of walkway with outdoor = (x + 8)*(x + 8)
= (
+ 16x + 64) 
Area of walkway = Area of walkway with outdoor - Area of the square outdoor
= (
+ 16x + 64) - 
= 16x + 64
Area of walkway = 16(x+4) 
37.5% of $80 = $30
Since it is marked up, you add $30 to the current price.
$80 + $30 = $110.
Ralph (r): a + 5
Alphonse (a): a
Ralph + Alphonse = Total
(a + 5) + (a) = 73
2a + 5 = 73
2a = 68
a = 34
Ralph: a + 5 = 34 + 5 = 39
Answer: Ralph has 39 marbles, Alphonse has 34 marbles
