Answer:

$1.75

Step-by-step explanation:

Set up a system of equations where x is the cost of a corndog and y is the cost of a coke:

3x + y = 7.1

2x + 2y = 7.2

Solve by elimination by multiplying the top equation by -2

-6x - 2y = -14.2

2x + 2y = 7.2

Add them together:

-4x = -7

x = 1.75

So, the cost of one corndog is $1.75
