Answer:
Consider the complete question is,
'For each customer, a bakery charges p dollars for the first loaf of bread bought by the customer and charges q dollars for each additional loaf bought by the customer. What is the value of p ?
(1) A customer who buys 2 loaves is charged 10 percent less per loaf than a customer who buys a single loaf.
(2) A customer who buys 6 loaves of bread is charged 10 dollars.
Solution :
Since, the charges of first loaf = p dollars,
Charges for each additional loaf = q dollars
Thus, the total charges for x additional loaf = p + qx
Charges for 1 loaf = p,
Charges for 2 loaf per loaf = (p + q)/2
According to the question,
.....................(1),
Again according to the question,
p + 5q = 10 .....................(2),
Equation (2) - 5 × equation (1),
p + 4p = 10
5p = 10
⇒ p = 2
Hence, the value of p would be 2.
Answer:
meters.
Step-by-step explanation:
To find diver's final location relative to the surface of water we will subtract from
because diver dives away another
from his previous location of
.
Now we will convert our mixed fraction into improper fraction and then we will find a common denominator.
Now let us convert our answer in mixed fraction.

Therefore, diver's final location relative to the surface of the water is meters.
