Answer:
$8.40
Step-by-step explanation:
The formula for calculating simple interest is
principal * interest rate * time .
Plugging 140 into the principal, or starting value, 3% as the interest rate, and 2 (years) for the time, we get 140*0.03*2 = 8.4, or $8.40 as our answer. Note that 3% turned into 0.03 as turning a percentage into a decimal requires us to divide the decimal by 100
If I'm correct and the ^ stands for multiplication then the answer should be 5.
The picture is my work just ignore the fraction.
The constant of proportionality is 5. For every time the total area "A" is multiplied by one the length is multiplied by 5.
