20 I = prt Financial Literacy
Arnold puts $580 into a savings account. The account pays 3% simple interest. How much will he earn in 5 years? I = prt Interest earned?

21 I = prt Financial Literacy
Arnold puts $580 into a savings account. The account pays 3% simple interest. How much will he earn in 5 years? I = prt Principal?

22 I = 580rt Financial Literacy
Arnold puts $580 into a savings account. The account pays 3% simple interest. How much will he earn in 5 years? I = 580rt Rate?

23 I = 580 · 0.03t Financial Literacy
Arnold puts $580 into a savings account. The account pays 3% simple interest. How much will he earn in 5 years? I = 580 · 0.03t Time?

24 I = 580 · 0.03 · 5 Financial Literacy
Arnold puts $580 into a savings account. The account pays 3% simple interest. How much will he earn in 5 years? I = 580 · 0.03 · 5 What is the simple interest?

25 I = 580 · 0.03 · 5 = $87 Financial Literacy
