What is the interest earned on $350.00 invested 4 years at a 5% simple interest?

So simple interest earned is [ (5% of 350) times 4]

so

percent means parts out of 100 so 5%=5/100=1/20

'of' can be translated as multiply

(1/20 times 350) times 4

[ (350/20) times 4]

[ (17.5) times 4]

[70]

70 is the answer
