Bank B will charge her the least amount of interest with a Total amount owed of $6,480

Step-by-step explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

To solve this problem we will be using the Simple Interest Formula as shown below.

A = P(1 + rt)

Where:

Now that we have the formula we can plug in the values for each bank and solve for the total amount they will charge Michelle.

Based on the calculations above we can see that Bank B will charge her the least amount of interest with a Total amount owed of $6,480

I hope this answered your question. If you have any more questions feel free to ask away at .

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
