Carla has a store that sells candles for 4 for 10 dollars. how many candles will she need to make 100 dollars?
i need the answer quick

She will need 40 candles to make 100 dollars

Step-by-step explanation:

Step 1: Determine price per unit of candle

The price per unit of candle can be expressed as;

Price per unit=Total cost of candles/Number of candles sold

where;

Total cost of candles=10 dollars

Number of candles sold=4

replacing;

Price per unit=10/4=2.50 dollars

This means that 1 candle will be sold for 2.50 dollars

Step 2: Number of candles needed to make 100 dollars

Number of candles sold=Total cost of candles/Price per unit

where;

Total cost of candles=100 dollars

Price per unit=2.5 dollars per candle

replacing;

Number of candles sold=(100/2.5)=40

She will need 40 candles to make 100 dollars

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?
