Fred paid $248 for a business suit. This was $55 less than the regular price of the suit. What was the regular price of the suit ?

Question

 This was from a packet my teacher gave us it is about soling equations.

Answer 1

Let variables represent...

 

s=sale price of suit

r=regular price of suit

d=amount of discount

 

So we can say...

(saleprice of suit)=(regular price of suit) - (amount of discount)

 

Let's substitute our variables...

s=r-d

 

Let's substitute the numbers we know for the variables...

      248=r-55

248+55=r-55+55.......add 55 to both sides

      303=r..................simplify

       ∴ r=303.............rewrite

 

Recognize that you can create your "math facts" (two

addition and two subtraction facts) for this problem from 

the numbers we have.  Fact #1 was used to solve this

problem.....

248+55=303.....addition, fact #1

55+248=303.....addition, fact #2

303-55=248......subtraction, fact #3

303-248=55......subtraction, fact #4
