7.EE.A.2: Understand that rewriting an expression in different forms can shed light on the problem — Practice

Concepts

A price $p$ increases by 8% due to a fee. Which expression correctly
represents the new total?

$p + 0.08p$

$p + 8$

$1.08p$ , but only when $p$ is a whole number

$0.08p$

The expression $1.05a$ is the single-multiplier form of a 5% increase
on $a$ . Which situation would most naturally use the expanded form
$a + 0.05a$ instead?

Explaining to someone why the total is the original amount plus a 5% addition

Quickly computing the final total for many different values of $a$ using a calculator

Writing the shortest possible expression for a spreadsheet formula

Comparing two different 5% increases without knowing either starting value

Procedures

new value after the decrease?
