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:
let cost of washer be x
cost of dryer be $745-x
we have
cost of washer =$95+($745-x)
x=$95+$745-x
x+x=$840
2x=$840
x=$840/2=$420
the cost of washer =$420
<h2>cost of drier </h2>
=$745-x=$745-420=$325
$325 is the cost of dryer.
