Barb has $800 and is spending $30 per week.Claire has $300 and is saving $20 per week.In how many week ,will Bard and Claire have the same amount of money?
Here is a really similar question that will help you:
Let \(x\) be the number of weeks.
Barb is SPENDING. So he/she is represented as \(800-30x\)
Clair is SAVING. So he/she is represented as \(300+20x\)
Set the two expression equal to each other in order to fufill the question.
Now solve for \(x\)
