Answer/Step-by-step explanation:
The equation that relates the proportional quantities would take the following form ---› , where,
y = amount of Grape juice (dependent variable)
x = amount of Apple juice (independent variable)
k = constant of proportionality (y/x)
✔️Using any of the given pair, say, (5, 8),
Constant of proportionality =
Substitute k = 1.6 in .
<em>An equation that represents the proportional relationship would be:</em>
Or
<em>How the equation would change if:</em>
y = amount of Apple juice (dependent variable)
x = amount of Grape juice (independent variable)
The constant of proportionality would change, that is using a pair, say, (8, 5),
Substitute k = 0.625 in .
<em>The equation would now be:</em>
.
