 To take a percent, move the decimal point of the percent two places to the left. 7% = 0.07
Then multiply:
12.60 • 0.07 = 0.88
12.60 + 0.88 = 13.48
The total cost is: $13.48
        
                    
             
        
        
        
Step-by-step explanation:
Let the son's age be x and man be y
y=26+x
y=8+3x
x=9
Son's age is 9
 
        
                    
             
        
        
        
6.3 many more cups of dry food will Maria's pet have eaten than Trenton's pet will have eaten over 2 seven-day weeks
<u>Step-by-step explanation:</u>
We have , Trenton and Maria record how much dry food their pets eat on average each day.• Trenton's pet: 4/5 cup of dry food• Maria's pet: 1.25 cups of dry food. Based on these averages . We need to find  how many more cups of dry food will Maria's pet have eaten than Trenton's pet will have eaten over 2 seven-day weeks . We need to find how much they eat for 14 days as:
Trenton's pet: 4/5 cup of dry food•
 With 4/5 per day , for 14 days :
⇒ 
⇒ 
⇒ 
Maria's pet: 1.25 cups of dry food.
With 1.25 per day , for 14 days :
⇒ 
⇒ 
Subtracting Maria's - Trenton's :
⇒ 
That means , 6.3 many more cups of dry food will Maria's pet have eaten than Trenton's pet will have eaten over 2 seven-day weeks
 
        
             
        
        
        
Answer:
point - slope form
  y - 1 = 3 (x-0)
Step-by-step explanation:
<u><em>step(i):-</em></u>
Given points are (0,1) and (2,7)
The slope of the line 
      
     
   m =3 
<u><em>Step(ii):-</em></u>
point -slope form
    y - y₁ = m(x-x₁)
Equation of the straight line passing through the point (0,1) and having slope 'm' = 3
    y - 1 = 3 (x-0)
   y -1 = 3x
  3x - y +1=0
Equation of the straight line passing through the point (0,1) and having slope 'm' = 3 is 3x -y +1=0
