C = 1.39 + 0.5(n - 1), where C is the cost and n is the number of days
C = 1.39 + 0.5(6)
C = $4.39
Answer:
k is 2/3 and y is -1/3 when x is -0.5.
Step-by-step explanation:
The direct variation relationship is y = kx, where k is the const. of var.
Subbing 3 for x and 2 for y, 2 = 3k, or k = 2/3.
Now, if x = -0.5, y = (2/3)(-1/2) = -1/3
k is 2/3 and y is -1/3 when x is -0.5.
If this is an exponent, it would be 4 x 4 x 4 x 4 x 4 in expanded form.
