Mary should charge $8.0 per ounce.
From the question the herbal tea is a blend of 2 kinds of mint:
75% spearmint- $2.25
25% peppermint-$ 2.75.
The cost of producing one ounce is:
75% spearmint- $2.25 + 25% peppermint-$ 2.75. =$5
The cost of the tea if it is to be sold 1.6 times will be calculated thus;
$5×1.6= $8.0
To get the new cost of the mint tea blend, the old cost is thus, multiplied by 1.6. This gives us the new cost of the mint tea blend.
Therefore cost per ounce will be $8.0

Answer:
(1,1)
Step-by-step explanation:
U have to subtract the 2 numbers.
The bigger number is 1,787 * 10^9
the smaller is 8,867*10^8
Now convert the bigger to the same power of 10
1,787 * 10^9 = 17,87 * 10^8
17,87 * 10^8 - 8,867*10^8 = 9,003 * 10^8
