**Fred invests $630 in his savings account each year. He earns an interest at a rate of 4.5% per year. After the first year, how much is in Fred’s account?**

**Answer:**

630 * (1 + .045)

You take 630 and you times it by .045 and you get 28.35 then you take 630 + 28.35 = 658.35

630=100% & x=4,5%

x:630=4,5:100

x=630*4,5/100

x=28,35

28,35+630=658,35
