Question

Kit bought a soft drink and a sandwich for $9.00. What was the price of each if the sandwich cost 3.5 times much as the soft drink?

Answer 1

Let the cost of the soft drink = C   then the price of the sandwich was 3.5 times as much = 3.5C

 

And

 

C + 3.5C  = Total Cost

 

C + 3.5C  =   9

 

4.5C = 9    divide both sides by 4.5

 

C = 9/4.5  =  $2.00   for the soft drink

 

And  3.5C = 3.5(2.00)  = $7.00   cost of the sandwich

Answer 2

The sandwich is $7. the drink is $2. 3.5x+x is 4.5x (x is how much the soft drink costs). 9/4.5 is 2. 2x3.5 is 7.
