Answer:
15.4 pounds
Step-by-step explanation:
Given: Roberto got a puppy from the shelter, it weighed 11 pounds. The puppy gained 40% of it's original weight in the first month that Roberto had it.
To Find: How much did the puppy weigh after the first month.
Solution:
Weight of puppy when Roberto got it from shelter = \(11\) \(\text{pounds}\)
percentage gain in puppy's weight after one month = \(40\) % of original weight
therefore,
Total weight of Roberto's Puppy after first month = \(140\% (\text{original weight})\)
that is,
Total weight of Roberto's Puppy after first month= \(\frac{140}{100}\times (\text{original weight})\)
putting value,
Total weight of Roberto's Puppy after first month= \(\frac{140}{100}\times 11\)
=\(\frac{140\times11}{100}\)
=\(\frac{1540}{100}\)
=\(15.4\) \(\text{pounds}\)
Hence, the puppy weighs \(15.4\) \(\text{pounds}\) after the first month
