Hana sold 4/7 of her stamp collection for $28. How much would she have earned from selling the entire collection?
Hana sold 4/7 of her collection for $28, so 1/7 of her collection represents: 28/4 = $<<28/4=7>>7.
And as a result, the entire collection represents: 7 * 7 = $<<7*7=49>>49.

Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
You are solving math problems. Here are some examples of how to solve the task:

Micah bought envelopes to send, and depending on the weight of the envelope he will need more stamps. If an envelope weighs more than 5 pounds, he will need 5 stamps. If it weighs less than that, it will only need 2 stamps. If he bought 52 stamps with 6 envelopes that weigh less than 5 pounds, how many envelopes in total did Micah need to buy?Micah had to buy 6*2=<<6*2=12>>12 stamps for 6 envelopes less than 5 pounds.
He has 52-12=<<52-12=40>>40 more stamps to buy.
There are 40/5=<<40/5=8>>8 envelopes that weigh more than 5 pounds.
Micah needed to buy 8+6=<<8+6=14>>14 envelopes.

If the number of dogs in the neighborhood was originally half the number of cats in the neighborhood before twenty new dogs were born, and now there are twice as many dogs as cats, how many cats were in the neighborhood, to begin with, if there are 20 cats now?Now there are twice as many dogs as cats, and if the number of cats is 20, there are 2*20=<<2*20=40>>40 dogs.
Before twenty new ones were born, the number of dogs in the neighborhood originally was 40-20=<<40-20=20>>20
If the number of dogs in the neighborhood was originally half the number of cats in the neighborhood, there were 20*2=<<20*2=40>>40 cats in the neighborhood.

Now, solve this next question in the style of the above examples:

Hana sold 4/7 of her stamp collection for $28. How much would she have earned from selling the entire collection?

### Response:
Hana sold 4/7 of her collection for $28, so 1/7 of her collection represents: 28/4 = $<<28/4=7>>7.
And as a result, the entire collection represents: 7 * 7 = $<<7*7=49>>49.
