Answer:
Interest paid to Laura is $320
The final amount is $2320
Step-by-step explanation:
Recall that the equation for simple interest is where
is the final amount,
is the principal/initial value,
is the annual interest rate, and
is the time in years.
Therefore, if the final amount is $2320, then the interest paid to Laura is $2320 - $2000 = $320
Steps of adding -6 + 4 using number line are as following:
1) Draw a number line by ranging from -10 to +10.
2) Point out -6 on the number line.
3) Because 4 is added to -6 on the number line, please move 4 number right to -6 on the number line. We always go right in addition and go left in subtraction on the number line.
4) The number we reach 4 on right side would be our final sum.
5) From the number we can clearly see that moving 4 number on right to -6, we get -2.
So, final answer is -2.
