Answer 1

10% of 11 is 1.1×4=4.4
4.4+11=15.4
15.4 pounds

Answer 2

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
