Answer:
$10.50
Step-by-step explanation:
We can make an equation
2.50+2x=?
x=4 because we are riding 4 miles.
so it's 2.5+2*4=?
let's solve
2.5+8=$10.50
 
        
             
        
        
        
Answer:
The number 10 is the base
 
        
             
        
        
        
(5 Neighbors) x (($1.00 Box) + (? Plant) + ($3.00 Gloves)) = 42.50
5 x (1 + x + 3) = 42.50
Combine in parens. 
5 x (4 + x) = 42.50
Distribute. 
20 + 5x = 42.50
Subtract 20 from both sides. 
5x = 22.50
Divide both sides by 5. 
x = 4.50
Thats the cost of each plant. 
Check. 
5 x (1 + 4.50 + 3) 
5 x 8.50 = 42.50
