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

Answer:

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

Step-by-step 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:

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