Turn the English into Algebra: Letters: Use a for Alex's work rate; Use s for Sam's work rate; 12 days of Alex and Sam is 10 tables, so: 12a + 12s = 10. 30 days of Alex alone is also 10 tables: 30a = 10. We are being asked how long it would take Sam to make 10 tables. Solve: 30a = 10, so Alex's rate (tables per day) is: a = 10/30 = 1/3
