898.55 - 118.3 = 780.25
780.25 = t
Your answer is D
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,
