Mr Samuel has 150 pennies in two jars. There are 40 more pennies in one jar than in the other. How many pennies are in each jar?
55 in the emptier jar and 95 in the other jar.
Here is some insight to the process.
Let x = pennies in one jar and X+40 = pennies in the other.
x + x + 40 = 150
2x = 110
x = 55
x + 40 = 95
