Final answer:
Using a system of linear equations, the cost of one burrito platter is found to be $32, and the cost of one taco platter is $26.
Step-by-step explanation:
We have a system of linear equations representing the cost of the burrito and taco platters from Carmen's favorite Mexican restaurant. Let B be the cost of a burrito platter and T be the cost of a taco platter. The two scenarios give us the following equations:
- B + T = $58 (one burrito platter and one taco platter)
- 2B + T = $90 (two burrito platters and one taco platter)
To solve this system, we can subtract the first equation from the second, which gives:
2B + T - (B + T) = $90 - $58
B = $32, which means the cost of one burrito platter is $32.
Substitute B in the first equation:
32 + T = $58
T = $58 - $32
T = $26, which means the cost of one taco platter is $26.
Therefore, a burrito platter costs $32, and a taco platter costs $26.
