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?
Hello sandwich!
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.
800−30x=300+20x
Now solve for x
