Answer this question:John buys 3 dress shirts. They sell for $20 each. He also has to pay 10% tax on everything. How much did he pay in total?
The shirts cost 3 * $20 = $60 before tax. The tax cost $60 * .1 = $6. So in total they paid $60 + $6 = $66.
The answer is 66.

Answer this question:John decides to get a new phone number and it ends up being a recycled number. He used to get 20 text messages a day. Now he is getting 55. Assuming the number of texts his friends send has not changed, how many text messages per week is he getting that are not intended for him?
He is getting an extra 55 - 20 = 35 text messages per day. So he is getting an extra 35 * 7 = 245 text messages per week.
The answer is 245.

Answer this question:The balance of Pam's bank account tripled during the year. At the end of the year, Pam withdrew $250. If her current balance is $950, how much did she have in the bank account at the beginning of the year?
First, we have to come up with the balance before her withdrawal. $950 (current) + $250 (withdraw) = $1200. Now since we know that is triple, we divide by 3. $1200 / 3 = $400.
The answer is 400.

Answer this question:John runs a website that gets 30000 visits a month, for a normal 30 day month. He gets $.01 per visit. How much does he make per day?

The answer is 10.
