The amount of tips that Casey earned in last week is option(D) $780.25
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given,
Casey's Hourly rate without tip = $4.55
Total hours worked by Casey in last week = 26 hours
Total amount earned without tip = 26×4.55 =$118.2
Total amount earned with tip = $898.55
Tip = 898.55 - 118.2 = $780.25
Hence, The amount of tips that Casey earned in last week is option(D) $780.25

Answer:
Step-by-step explanation:
Equations and inequalities are both mathematical sentences formed by relating two expressions to each other. In an equation, the two expressions are deemed equal which is shown by the symbol =. ... An equation or an inequality that contains at least one variable is called an open sentence.
An inequality compares two values, showing if one is less than, greater than, or simply not equal to another value. a ≠ b says that a is not equal to b. a < b says that a is less than b. a > b says that a is greater than b. (those two are known as strict inequality)
