John has $5,000 in his savings. That’s the total. He has to give his sister $50 for her birthday. He also spends $450 for his car payment. We can easily put this into an equation. 50x-450=5000 Now we have to solve it. 50x-450=5000 -450 -450 50x=5000-450 50x=4550 50x/50=4550/50 x=91 So it will take 91 months to spend his $5,000.
