In a factory, Machine A was turned on first and it produced 215 wontons. Then Machine A and Machine B were turned on at the same time to continue production. For every 3 wontons Machine A produced, Machine B produced 5 wontons. Machine B produced 70 less than
35 of the total number of wontons produced. How many wontons were produced altogether?

Make u the same (1) x 5 = (3) |
Machine A (1) |
Machine B (2) |
Make u the same (2) x 3 = (4) |

+ 15 u |
+ 3 u |
+ 5 u |
+ 15 u |
|
After |
15 p + 350 |
3 p + 70 |
3 p - 70 |
9 p - 210 |
5 p |
From (3)
1075 + 15 u = 15 p + 350
15 u = 15 p + 350 - 1075
15 u = 15 p - 725
From (4)
0 + 15 u = 9 p - 210
15 u = 9 p - 210
(3) = (4)
15 p - 725 = 9 p - 210
15 p - 9 p = 725 - 210
6 p = 515
Number of wontons that were produced altogether
= 5 p
= 5 x 515
= 2575
Answer(s): 2575
