Solve the given expression.

Question

3200+25/100(3200)= 400d

Answer 1

3200+25/100(3200)= 400d

How I understand the equation is

(3200+(25/100))(3200) = 400d

then if it the correct equation we can divide both sides by 400:

(3200+(24/100))(3200*400) = d

(3200*100 + 24)/(3200*100*400)=d

solve for d

if is not the equation, please post the right one.

Answer 2

First, put parentheses around each appropriate term:

 

3200 + (25/100)(3200) = 400 d

 

Step 2, divide 25 by 100:

 

3200 + (.25)(3200) = 400 d

 

Step 3, multiply .25 by 3200:

 

3200 + 800 = 400 d

 

Step 4, divide each term by 400:

 

8 + 2 = d

 

Step 5, add 8 + 2 to obtain the final answer:

 

d = 10

 

Step 6, check your answer:

 

3200 + 800 = 4000

 

CORRECT!
