Answer:
$4884.75
Step-by-step explanation:
The amount in a simple interest account is given by the formula ...
A = P(1 +rt)
Here, we have principal P=$4500, interest rate r=0.0285, and time t=3. Then the amount in the savings account will be ...
A = $4500(1 +.0285·3) = $4500·1.0855 = $4884.75
Answer:
x = - 6
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = - 9 when x = 3, thus
k =
=
= - 3
y = - 3x ← equation of variation
When y = 18, then
18 = - 3x ( divide both sides by - 3 )
x = - 6
