Answer:
9.60 dollars tip is $1.60
Step-by-step explanation:
It should be noted that the expansion of the equation (ac+b-d)(a² - c) will be a³c + ac² + a²b - bc - a²d + cd.
<h3>How to illustrate the information?</h3>
It should be noted that an equation is used to show the relationship that occur between the variables that are illustrated.
In this case, it should be noted that the equation
(ac+b-d)(a² - c) will be solved accordingly. This will be:
(ac+b-d)(a² - c)
Open the parentheses
a³c + ac² + a²b - bc - a²d + cd
Therefore, it should be noted that the expansion of the equation (ac+b-d)(a² - c) will be a³c + ac² + a²b - bc - a²d + cd.
