Pls help:

John has a number of 10-cents coins and Mary has a number of 50-cents coins. John has 6 more coins than Mary but Mary has $9.00 more than John. How much does John has?

Number of coins;
Mary --> 1 unit
John --> 1 unit + 6

Amount;
Mary --> 1 unit * 50 = 50 units
John --> 10 units + 60

Since Mary has 900cents more than John;
50units - 10units - 60 => 900
40units => 900 + 60 = 960
1unit => 960 / 40 = 24

John;
10 * 24 + 60 = 300cents = $3.00

Sorry, I’m new here. Was surfing these forum and trying to contribute :-). And came across this question. After reading it, I have one question. Can you tell me why divide by 40?


i.e the step 960/40.
