Answer:
6
Step-by-step explanation:
xy=k
Value of k ; when ; x = - 3 and y = - 2
Put x = - 3 and y = - 2 into the equation :
(-3)(-2) = k
-3 * - 2 = k
6 = k
The constant of variation k = 6

Answer:
<h3>C. 800</h3>
Step-by-step explanation:
Given the equation used to calculate the amount of profit, p, made from selling n candy bars expressed as p = 1.50n – 500
To find the number of candies sold for $700, we are going to substitute p = $700 into the given expression and find n as shown;
700 = 1.50n - 500
Add 500 to both sides
700+500 = 1.50n-500+500
1200 = 1.50n
Divide both sides by 1.50
1200/1.50 = 1.50n/1.50
800 = n
Rearrange
n = 800
Hence 800 candy bars must be sold to make $700 profit
