Answer:
9000
Step-by-step explanation:
$13200 is the cost to produce all of the cds.
if they sell them all, for $15 each, we get $4200,
so, if we subtract the cost to produce them, versus what they made off them we get:
$9000.
the profit is $9000
Answer:
A(t) = 0.825 g
Step-by-step explanation:
To solve this for amount remaining, we will use the equation;
A(t) = A_o × (½)^(t/t_½)
We are given;
Initial amount; A_o = 6.6 g
Half life; t_½ = 14
Time elapsed; t = 42
A(t) is amount of substance remaining
Thus;
A(t) = 6.6 × (1/2)^(42/14)
A(t) = 6.6 × (1/2)³
A(t) = 6.6 × ⅛
A(t) = 0.825 g
