A Trip to the Beach (Solve multi-step word problems involving estimation of sums and differences for decimal numbers)

The video tutorial follows Olivia as she plans her lunch expenses after a beach trip. With $9.25, she intends to buy a chicken sandwich and water, estimating her leftover money to see if she can afford ice cream. The tutorial demonstrates two methods for calculating the exact leftover amount: one using addition and subtraction, and another using step-by-step subtraction.
