1. Saiz buys a Playstation 5 for $500 with a credit card carrying a 21% Annual Percentage Rate (APR) and each month she will pay
back $10. By the time she finishes paying off her credit card, what will be the real, total cost of the Playstation 5?
2. After buying the Playstation 5, Saiz drives home and her tire goes flat. When getting a new tire for her car, she charges $100 on a different credit card carrying an 18% APR and each month she will pay back $5. By the time she finishes paying off her credit card, what will be the real, total cost of the brand new tire?
I’m not the best with words but first you would have to treat the greater sign as a = sign. So.. -2x =6 / / -2 -2 X = -3 and then you would change the sign to a less than sign because you divided by a negative.
