Hi there...

Problem...

----------------

The "Drive-Through"-menu...:

------------------------------------------

Nr.1. = 1 burrito and 1 coffee for $5.60.

Nr.2. = 2 burritos and 3 coffees is $12.55.

-------------------------------------------------

Determine the cost of one burrito?

-------------------------------------------------

We know the following...

----------------------------

(a+b)=5.60

((2a)+(3b))=12.55

----------------------------

I hope that helped a bit?

Kind regards

1B + 1C = 5.60

2B + 3C = 12.55 two equations, two unknowns......solve for B Multiply 1st equation by -3 to get:

-3B-3C = -16.8 Now add 2nd and third equations to get:

-B = -4.25

B=4.25 Done !
