Answer: The system of equations are

x + y = 10

3.75x + 2.5y = 35

Step-by-step explanation:

Let x represent the number of cupcakes that Camila bought.

Let y represent the number of brownies that Camila bought.

She bought a total of 10 cupcakes and brownies altogether. This would be expressed as

x + y = 10

Camila and her children went into a bakery and she bought $35 worth of cupcakes and brownies. Each cupcake costs $3.75 and each brownie costs $2.50. This would be expressed as

3.75x + 2.5y = 35
