we need to set up a system of equations based on the given information.Let's define the variables:s = cost for each breakfast burritoS = cost for each small glass of milkFrom the given information, we can write the following equations:Equation 1: s + S = 2.10 (The cost for a breakfast burrito and a small glass of milk is
5.15)Now, let's solve this system of equations.Step 1: Solve Equation 1 for s:s = 2.10 - SStep 2: Substitute the expression for s into Equation 2:2(2.10 - S) + 3S = 5.154.20 - 2S + 3S = 5.15S = 5.15 - 4.20S = 0.95Step 3: Substitute the value of S back into Equation 1 to find s:s + 0.95 = 2.10s = 2.10 - 0.95s = 1.15Therefore, the cost for each breakfast burrito is
0.95.
