Question:
Heather bought a large bag of bird seed and used 24% of the bag. How many pounds were originally in the bag if there are 15.2 pounds left?
Answer:
There were 20 pounds of seed in bag originally
Solution:
Given that,
Heather used 24 % of bag
There are 15.2 pounds left
To find: Pounds of seed in bag originally
Let "x" be the pounds of seed in bag originally
From given,
100 % - 24 % = 76 %
Thus 76 % of bag is unused
Also, given that there are 15.2 pounds left
Therefore, we can say,
76 % of x = 15.2
[tex]76 \% \times x = 15.2\\\\\frac{76}{100} \times x = 15.2\\\\0.76x = 15.2\\\\x = \frac{15.2}{0.76}\\\\x = 20[/tex]
Thus there were 20 pounds of seed in bag originally
