Step 1: Define variables and set up the equations. Let x be the number of 50 Kobo notes. Let y be the number of 10 Kobo pieces. The total number of notes and pieces is 440: x + y = 440 (1) The total value is N60. Since 1 Naira (N) = 100 Kobo, N60 is equal to 60 × 100 = 6000 Kobo. The total value equation is: 50x + 10y = 6000 (2) Step 2: Express one variable in terms of the other. From equation (1), we can express y in terms of x: y = 440 - x Step 3: Substitute this expression into equation (2) and solve for x. Substitute y = 440 - x into 50x + 10y = 6000: 50x + 10(440 - x) = 6000 50x + 4400 - 10x = 6000 Combine the terms with x: 40x + 4400 = 6000 Subtract 4400 from both sides: 40x = 6000 - 4400 40x = 1600 Divide by 40: x = (1600)/(40) x = 40 The number of 50 Kobo notes is 40. The final answer is 40. That's 2 down. 3 left today — send the next one.
