Answer:
<u>Janet's interest is $3.90 every month.</u>
Step-by-step explanation:
First, you need to set up a proportion to find Janet's interest:
0.65%/100 = x/600
Step 1: Cross-multiply.
0.65/100/100 = x/600
(0.65/100)*(600)=x*(100)
39/10=100x
Step 2: Flip the equation.
100x=39/10
Step 3: Divide both sides by 100.
100x/100=39/10/100
x=39/1000 (0.039)
Then move the decimal twice to the left to find the dollar amount:
0.039 ⇒ 3.90
Janet's interest is $3.90 every month.
