Start by naming the process: Read what the problem is asking, choose the matching rule, write the setup, and then simplify one step at a time. The setup/work is Use I = Prt. Change 5% to 0.05, then multiply: 100 􀀂 0.05 􀀂 1 =$5 . So the 􀀂nal answer is $5 .  \n2. A good way to think about this is: Read what the problem is asking, choose the matching rule, write the setup, and then simplify one step at a time. The setup/work is I = 200 􀀂 0.10 􀀂 2. Step by step: 200 􀀂 0. 10 = 20, then  \n20 􀀂 2 = $40 . So the 􀀂nal answer is $40 .  \n3. Step by step: Read what the problem is asking, choose the matching rule, write the setup, and then simplify one step at a time. The setup/work is I = 1000 􀀂 0.03 􀀂 4 = 30 􀀂 4 = $120 . So the 􀀂nal answer is $120 .  \n4. Take it one move at a time: Read what the problem is asking, choose the matching rule, write the setup, and then simplify one step at a time. The setup/work is I = 500 􀀂 0.06 􀀂 1 = $30 . So the 􀀂nal answer is $30 .  \n5. Start by naming the process: Read what the problem is asking, choose the matching rule, write the setup, and then simplify one step at a time. The setup/work is I = 800 􀀂 0.05 􀀂 2 = 40 􀀂 2 = $80 .
