What is $300 at 5% annual interest for 7 years

Ok so first find 5%

percent measn parts ou fo 100

5%=5/100

'of' means multiply

interest is annual

so

what happens is

5% of 300 first year or 100%+5% becuase we find 5% then add taht to 300

then

secondn year you do 5% of that pervious year or 100%+5%

so we sense a pattern

100+5=105

1.05=105%

each year we multiply the thing by 1.05 since that is the new value

7 years so

300 times 1.05 times 1.05 times 1.05 times 1.05 times 1.05 times 1.05 times 1.05=5125.78

answer is $5125.78 after 7 years
