I believe you just multiply the two numbers together and get 2.665
<span>21x+28=14
x= -2/3 or -0.666666666
</span><span>9x+12y=6
x=2/3 or .666666666
y=0</span>

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
