Kelly makes 4 candles per hour (12/3=4). Lee makes 6 candles per hour (6/1=1). In 8 hours, Kelly makes 32 candles (4*8=32). In 8 hours, Lee makes 48 candles (6*8=48). The difference in the numbers of candles is 16 (48-32=16).

charle [14.2K]

Answer:

80n+20=total cost

Step-by-step explanation:

We don't know the value of n, but we don't need it for an expression. We know that the family has to pay $80 per night that they stay at the hotel. Modeling this would look like: 80n (80*n for nights). Also, we know that the family MUST pay a $20 fee. So, we can add that on to the expression to look like this, 80n+20=total cost.

Hope this helps!

Have a nice evening.
