Answer:
5 ; 5
Explanation:
Let us assume that the postcard be X
And the letters be Y
So there are two equations which are presented below:
X + Y = 10 - equation 1
$0.28X + $0.44Y = $3.60 - equation 2
Now we simplify the equation 2 by multiplying with the 100 and dividing by 4
7X + 11Y = $90
Now we substitution the both equations
X + Y = 10
7X + 11Y = $90
Multiplied by 7 in first equation
So,
7X + 7Y = 70
7X + 11Y = $90
4Y = 20
Y = 5
As we know
X + Y = 10
So, X would be
= 10 - 5
= 5
Answer:
4.27 days
Explanation:
Initial taste quality = 1
Quality of tastiness declines using this function
Q(t) = 0.85^t ( t in days )
<u>Determine when the taste quality will be 1/2 of original value</u>
i.e. when Q(t) = 1/2
1/2 = 0.85^t
= In ( 2 ) = - t ( In 0.85 )
∴ t = - In (2) / In (0.85)
= 4.265 days ≈ 4.27 days
