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 = [tex]11[/tex] [tex]\text{pounds}[/tex]
percentage gain in puppy's weight after one month = [tex]40[/tex] % of original weight
therefore,
Total weight of Roberto's Puppy after first month = [tex]140\% (\text{original weight})[/tex]
that is,
Total weight of Roberto's Puppy after first month= [tex]\frac{140}{100}\times (\text{original weight})[/tex]
putting value,
Total weight of Roberto's Puppy after first month= [tex]\frac{140}{100}\times 11[/tex]
=[tex]\frac{140\times11}{100}[/tex]
=[tex]\frac{1540}{100}[/tex]
=[tex]15.4[/tex] [tex]\text{pounds}[/tex]
Hence, the puppy weighs [tex]15.4[/tex] [tex]\text{pounds}[/tex] after the first month
