ed gets a paycheck weekly. she spent half of it.she earned 50 dollars. she ended up with 150 left.how much was her weekly paycheck
+27 So, the easiest way to solve this is to work backwards. Ed ends up with a grand total of $150. Before that, she earned an extra $50, so we subtract that from $150 leaving us with $100. If she spent half her paycheck and ended up with $100, then we can multiply that $100 by 2 giving us her initial weekly paycheck: $200
Here's the work in normal form:
150
-50
100
x2
200
