Final answer:
To find the cost of each type of platter, set up a system of equations and solve for the values of x and y. A burrito platter costs $25.50 and a taco platter costs $18.75.
Step-by-step explanation:
To find the cost of each type of platter, we need to set up a system of equations. Let's assume the cost of a burrito platter is x dollars and the cost of a taco platter is y dollars.
We can set up two equations to represent the total cost of the party trays:
- 4x + y = 207
- 4x + 5y = 299
We can solve this system of equations using the method of elimination or substitution to find the values of x and y.
By solving the system, we find that a burrito platter costs $25.50 and a taco platter costs $18.75.
