Money word problems worksheet for practicing addition and subtraction with real-life scenarios.

Explanation:
Let's solve each problem step by step.

1. John had $42.50 more than Jack who has $22.30.
To find how much money John has, we add the amount Jack has to the extra amount John has.
So, we add $22.30 and $42.50.
$22.30 + $42.50 = $64.80
So, John has $64.80.

2. Henry had $31.80 and then bought ice-cream for $27.50.
To find how much he has left, we subtract the cost of the ice-cream from the amount he started with.
So, we subtract $27.50 from $31.80.
$31.80 - $27.50 = $4.30
So, Henry has $4.30 left.

3. Chris has $73.60. He needs $94.20 to buy some revision books.
To find how much more money he needs, we subtract the amount he has from the amount he needs.
So, we subtract $73.60 from $94.20.
$94.20 - $73.60 = $20.60
So, Chris needs $20.60 more.

Final Answer:
1. $64.80
2. $4.30
3. $20.60
