Using the principle of proportional relationship, the amount of weight lost by hedgedog in 120 days is 3.6 oz
Proportional relationships are defined thus :
Taking a piar of points :
-0.24 = 8k
Divide both sides by 8
(-0.24/8) = k
k = - 0.03
Hence, hedgedog loses weight at a rate of - 0.03 oz per day.
The amount of weight lost in 120 days :
The proportional relationship = y = - 0.03x
Substitute x into the equation
y = -0.03(120)
y = - 3.6 oz
Therefore, the amount of weight lost in 120 days is 3.6 oz.
