The Larsen family bought 3 jumbo burritos and 2 regular burritos for 13.65. The Russo family bought 5 jumbo burritos and 2 regular burritos for 20.23. Does a jumbo burrito cost more than 3.00?

Is this a system of equations in two variables?

Yes, it is.
 
Wow! That's two in a roll. Good.
 
Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
