Question

Principal Time. Rate
$470. 10 days. 9%

Whats the interest?

Answer 1

• Principle=P=470
• Time=T=10
• Rate =R=R=9%

Interest be I

If interest is daily

• I=PRT/100
• I=470(10)(9)/100
• I=4230/10
• I=423$

If interest is monthly (30days)

• I=(470)(1/3)(9)/100
• I=470(3)/100
• I=1410/100
• I=14.10$

Answer 2

$ 1.20

Explanation:

`\sf Time = 10 \ days = (10)/(365)=(2)/(73)`

`Interest = Principal * time *rate\\\\\\=470*(2)/(73)*(9)/(100)\\\\= 1.20`

= $ 1.20
