1. the amount of money you have spent, s, and

how much money you have left, m

1. the number of apple slices remaining, r, and

the number of apple slices eaten, e

Explanation:

Problem 1:

Step1: Analyze variable dependency

To find dependent and independent variables, we check which variable depends on the other. Distance \( d \) traveled depends on speed \( s \) (since distance = speed × time, and if time is constant or speed determines distance).

Step2: Identify variables

Dependent variable: \( d \) (distance depends on speed). Independent variable: \( s \) (speed causes change in distance).

Step1: Analyze variable dependency

Calories \( c \) in a snack depend on the amount \( a \) of the snack (more snack means more calories, generally).

Step2: Identify variables

Dependent variable: \( c \) (calories depend on amount). Independent variable: \( a \) (amount causes change in calories).

Step1: Analyze variable dependency

Money left \( m \) depends on money spent \( s \) (if initial money is fixed, more spent means less left).

Step2: Identify variables

Dependent variable: \( m \) (money left depends on money spent). Independent variable: \( s \) (money spent causes change in money left).

Answer:

Dependent variable: \( d \) (distance traveled), Independent variable: \( s \) (speed)
