Step-by-step explanation:
Due to a typhoon, the harvest of cabbage in Baguio this month decreased from 125 tons to 80 tons. What is the percent of decrease?
If:
125 tons - 80 tons = 45 tons (decreased)
To find the percentage of decrease. we apply the rule of three, let's see:
(tons) ____ (%)
125 ----------- 100
45 ------------- y
\dfrac{125}{45} = \dfrac{100}{y}
45
125
=
y
100
Product of extremes equals product of means
125*y = 45*100125∗y=45∗100
125\:y = 4500125y=4500
y = \dfrac{4500}{125}y=
125
4500
\boxed{\boxed{y = 36}}\Longleftarrow(percent\:of\:decrease)
y=36
⟸(percentofdecrease)
Answer:
percent of decrease = 36 %
