P is the principal amount, $12000.00.
r is the interest rate, 5% per year, or in decimal form, 5/100=0.05.
t is the time involved, 3....month(s) time periods.
Since your interest rate is "per year" and you gave your time interval in "month(s)" we need to convert your time interval into "year" as well.
Do this by dividing your time, 3- month(s), by 12, since there's 12 months in 1 year.
So, t is 0.25....year time periods.
To find the simple interest, we multiply 12000 × 0.05 × 0.25 to get that:
The interest is: $150.00
Usually now, the interest is added onto the principal to figure some new amount after 3 month(s),
or 12000.00 + 150.00 = 12150.00. For example:
If you borrowed the $12000.00, you would now owe $12150.00
If you loaned someone $12000.00, you would now be due $12150.00
If owned something, like a $12000.00 bond, it would be worth $12150.00 now.

Answer:
Step-by-step explanation:
Plug in -7 for the variable a.
9x - 6(-7) = -7
Follow PEMDAS. Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x.
Multiply -6 with -7
9x - 6(-7) = -7
9x + 42 = -7
Isolate the variable x. Subtract 42 from both sides
9x + 42 (-42) = -7 (-42)
9x = -49
Divide 9 from both sides
(9x)/9 = (-49)/9
x = (-49)/9
x = ~5.44 (rounded)

To find which store has a better deal we are going to have to find the unit price per pen. To do this we do the following:
2.56/8 and 2.286 after doing both divisions we find that the cost of price per pens is .32$ from Nancy and .38$ from Joe.
