We are given that y varies jointly as x and z
Mathematically,
Where k is the constant of proportionality.
When x = 5, y = 80, and z = 8
So, the relationship becomes
What is y when x = 16 and z = 2?
Therefore, the value of y is 64
Answer:
-2 is the slope
Step-by-step explanation:
To solve part a, do the following.
49.84-44.50=<span>5.34
5.34/44.50=x/100
after solving the proportion, x would be equal to 12.
To solve part b, do the following.
50+12=62
</span>To solve part c, do the following.
The amount of the tip is:
x/<span>57.50=62/100
which is </span><span>35.65
The total bill is:
35.65+</span>57.50=<span>93.15</span>
