Did you figure it out?

Solution:  We can set up and solve the following system of equations to solve this problem:

M = 0.8S

E = S + 5

M + S + E = 33

Next, we plug the values of M and E into the third equation because they’re both already in terms of S. Now we have an equation with one variable—S. We can solve it to find that S = 10, so M must be 8. Logan has answered 8 math questions.
