Answer:
In B) y = x/7 , the constant of proportionality is 7.
Step-by-step explanation:
Two quantities X and Y are said to be in proportion if and only if
X = kY or,
,
where k = Proportionality Constant.
Here, 7 is the constant of proportionality. Then,
A . y = 14x
here,
≠ 7
B . y = x/7
here,
= constant of proportionality .
C. y = x
here,
≠ 7
Answer:
<em>$195</em>
Step-by-step explanation:
