Answer:
$449.77
Step-by-step explanation:
The balance in account 1 can be found using the simple interest formula.
A = P(1 +rt)
A = $300(1 +0.045·3) = $340.50
The balance for account 2 can be found using the compound interest formula.
A = P(1 +r)^t
A = $100(1.03)^3 = $109.27
__
Darla's total balance will be ...
$340.50 +109.27 = $449.77
You would equal both expressions to each other.
then you will need to get rid of the square root around 'x+2' by multiplying it to the power of 2.
this will remove the square root. but what you do to one side you must to do the other. therefore, the other side will now be x^4+ 6x^3 +13x^2 +12x +4.
your new expression is
x^4+ 6x^3 +13x^2 +12x +4 =x+2
when you simplify your answer will be
x= -2
Rounded down it is simply 6,000.
1.50x = y that should be a good equation hopefully. If it’s wrong I’m so sorry. Also if I were to find the answer I need more of the context of the question
