Question

Sharon wants to start a savings account with the money she earns selling scented candles. She already has $50 and would like to save at least $90. She earns $2 for each candle she sells. How many candles should Sharon sell in order to meet her goal?

Answer 1

Answer:

She must sell as least 20 candles

Step-by-step explanation:

Sharon has 50 dollars

She makes 2 dollars per candle

Money in 50+2c

She needs at least 90

90≤ 50+2c

We need to solve this inequality

Subtract 50 from each side

90-50≤ 50-50+2c

40 ≤ 2c

Divide by 2

40/2 ≤ 2c/2

20 ≤ c

She must sell as least 20 candles

Answer 2

90-50=40 40 divided by 2 = 20. sharon needs to sell 20 candles
