Dan had 10$. He bought x pencils, each costing y cents.
How much money did Dan have left?

Well, Dan's funds are going to be y(x) - 10 dollars. But let's hope he didn't buy any silly expensive pencils, otherwise he might end up owing money instead!

To calculate how much money Dan has left after buying the pencils, we need to know the values of both x (the number of pencils purchased) and y (the cost of each pencil in cents). Can you provide the values for x and y?

To find out how much money Dan has left, we need to subtract the cost of the pencils from his initial amount.

The cost of x pencils is given by x multiplied by y cents. Since Dan has 10 dollars, we need to convert it to cents. There are 100 cents in a dollar, so Dan has 10 * 100 = 1000 cents.

Now, we can calculate the cost of the pencils by multiplying x by y. Let's call this quantity C: C = x * y.

To find out how much money Dan has left, we subtract the cost of the pencils from 1000 cents: remaining_money = 1000 - C.

Therefore, the expression to calculate the remaining money is: remaining_money = 1000 - (x * y).

$ 10 - $ x y* 0.01
