Write an expression that represents an increase of 5% over the original cost of $d as both a sum and product of d.

Sum equation:

Product equation:

Step-by-step explanation:

If we have an increase in 5% of d, that means that 5% of d () will be the total amount of money added to it.

However, we need to still count the original price of d, if we increase it by 5%!

So we add d to 0.05d.

is the sum equation.

Now, we can create the product equation for d by expanding the coefficients for the previous equation,  .

We can add like terms here: ! So we can just multiply this by d for our product equation.

Hope this helped!
