Answer:
y=6+2x
Step-by-step explanation:
 
        
             
        
        
        
We know that
<span>Olivia walks ---------> 1\4 of a mile to school
</span>
2/3   correspond to ------> 0.6666------> 66.67 %
3/3 correspond to--------> 1--------> 100%
so
if  (2/3)-----------> 1/4 mile
 (3/3)-------------> x
x=(1/4)/(2/3)-----> x=(1/4)*3/2-----> x=3/8------> x-0.375 miles
the answer is
<span>Ray walks to school 3/8 miles (0.375 miles)</span>
        
             
        
        
        
Let the cost of one book= x cents
Let the money john have= y cents
According to the question,
45x=y                                               ...eq(1)
(45+5)(x-5)=y                                   
50(x-5)=y                                         
50x-250=y                                        ...eq(2)
On subtracting (1) from (2).
(50x-250)-45x=y-y
5x-250=0
x=250/5
x=50
Thus, cost of each book is 50 cents and john has 2250 cents.
Hope it helps.
Don't feel shy in saying thx if it helps.
