Answer 2

Breakdown of Baked Pastries

To determine the quantity of each type of pastry baked, we can use the given information.

Given: - Total pastries baked: 800 - Quantity of cakes and éclairs: 503 - Quantity of éclairs and biscuits: 555

Let's denote: - Cakes as C - Éclairs as E - Biscuits as B

We can set up a system of equations to solve for the individual quantities of each type of pastry.

System of Equations

We have the following information: 1. Cakes and éclairs: \(C + E = 503\) [[1 #1]] 2. Éclairs and biscuits: \(E + B = 555\) [[2 #1]]

Solving the System

We can solve the system of equations to find the quantities of each type of pastry.

Subtracting equation 2 from equation 1: \[C - B = -52\]

Adding equation 1 and equation 2: \[2E = 1058\]

Solving for \(E\): \[E = 529\]

Substituting \(E = 529\) into equation 1: \[C + 529 = 503\] \[C = 503 - 529\] \[C = -26\]

Substituting \(E = 529\) into equation 2: \[529 + B = 555\] \[B = 555 - 529\] \[B = 26\]

Conclusion

The number of each type of pastry baked is as follows: - Cakes: 26 - Éclairs: 529 - Biscuits: 26
