Question

which expression represents the total amount of money arianna earns this week? 3c + 2c + 95c; 3 + 2 + 95; 3c + 2c + 95; 3 + 2 + 95c

Explanation:

Step1: Understand the context

We need to find the expression for total money earned, where \( c \) likely represents a unit of currency (like dollars per some task, or cents, etc.). So each term with \( c \) represents an amount of money, and a term without \( c \) would be a number without a monetary unit, which doesn't make sense for total earnings.

Step2: Analyze each option

• Option \( 3 + 2 + 95 \): This is just a sum of numbers, no monetary unit (since \( c \) is missing), so it can't represent total money.
• Option \( 3 + 2 + 95c \): Mixed terms, some with \( c \) and some without, inconsistent.
• Option \( 3c + 2c + 95 \): \( 95 \) has no \( c \), so it's a number without a unit, while \( 3c \) and \( 2c \) have units. Inconsistent.
• Option \( 3c + 2c + 95c \): All terms have \( c \), so they represent amounts of money (e.g., \( 3c \) could be 3 times a unit, \( 2c \) 2 times, \( 95c \) 95 times). Summing them gives total money.

Answer:

\( 3c + 2c + 95c \)
