Step1: Look for questions so we know what this question wants.

Step2: Ok, let's call the unknown number of beggars by a variable. I pick b.How many beggars are there and how much money have I?

How much money do start with? Let's call this m.

So

b = number of beggars (in people)

m = amount of cash I started with (in cents)

Step3: Translate sentences from the story into math statements.

This is a messy sentence, let's be careful with this one.If I were to give 7 cents to each of the beggars at my door, I would have 24 cents left

I start with some money. Then I lose some (7 cents to each beggar) because I gave it away. Then I have 24 cents left.

Math: (my starting money) - (7 cents to each beggar) = 24 cents

m - 7b = 24

See if you can put together another math statement from the second sentence, and then try and solve for b and m.
