Okay, let's break this down step-by-step:
* 5 hot dogs and 4 hamburgers cost 13.25 total
* 4 hot dogs and 5 hamburgers cost 13.75 total
* So the difference between the two options is 0.5 (13.75 - 13.25 = 0.5)
* We have 9 items total in the first option and 9 items total in the second option
* So the difference of 0.5 must be due to the cost difference of either 1 hot dog or 1 hamburger
* Let's assume 1 hot dog costs x dollars
* Then, 5 hot dogs would cost 5x
* And 4 hot dogs would cost 4x
* So 5x + 4x = 13.25
* 9x = 13.25
* x = 1.5 (cost of 1 hot dog)
*
* Now let's look at the second option:
* 4 hot dogs would cost 4x = 4 * 1.5 = 6
* 5 hamburgers would cost y dollars each
* So 4x + 5y = 13.75
* 6 + 5y = 13.75
* 5y = 7.75
* y = 1.55 (cost of 1 hamburger)
So in summary:
The cost of one hot dog is $1.50
The cost of one hamburger is $1.55
