Answer:
Step-by-step explanation:
Using the distributive property, we can write the expression as ...
(1 + 1 + 1 + 1)u = 4u
The coefficient of the variable is 4 in the simplified expression.
D would be the correct answer because you can use a variable (in this case they used D) in order to represent an unknown number. Because of this, you would be subtracting five from an unknown number (d). Hope this helps!
Answer:
$1680
Step-by-step explanation:
The equation for simple interest is I = PRT, where I = interest earned, P = principal/amount invested, R = rate as a decimal, and T = time in years.
Account 1:
I = (8000)(0.065)(6)
I = $3,120
Account 2:
I = (8000)(0.03)(6)
I = $1,440
$3120 - $1440 = $1680
