Answer: 
Step-by-step explanation:
Creating identical expressions involves changing quantities in a way that preserves the end values specified in the equation.
For instance, if Lei sold 4 carnations:

In the second equation listed, the expression (8 + 0.25c) was multiplied by 4, then by 0.25, for a total multiplicand of 1.
You can make a third equation through the same method. I'll multiply (8 + 0.25c) by 2, and then multiply that expression by 0.5 to keep the multiplicand unchanged:

If Lei sold 4 carnations:
0.5 * (16 + 2) = 9
This equation represents the same quantities as the other equations.
Answer:
$32.13
Step-by-step explanation:
Initial price = $36.00
Less 15 % = 0.15 × 36 = <u> -5.40
</u>
Sale price = $30.60
Plus 5 % = 0.05 × 30.60 = <u> 1.53
</u>
Amount paid = $32.13
