Question

The manager of a store increases the price of the bathing suits by 7%. Let t be the original price of a bathing suit. The new price is t + 0.07t. A. Find an expression equivalent to t + 0.07t.

Answer 1

`t+0.07t=t(1+0.07)=t(1.07)=1.07t`

Explanation:

There are a couple of equivalent expressions to the function
`t+0.07t`. For example:

`t+0.07t`

Factor:

`t+0.07t=t(1+0.07)`

If you add the terms inside the parentheses:

`t(1+0.07)=t(1.07)`

Basically you can add the like terms from the start and get the same result.

`t+0.07t=1.07t`

Therefore:

`t+0.07t=t(1+0.07)=t(1.07)=1.07t`
