Flask a contains photosynthetic green algae in water while flask b contains water with no algae. both are placed under lights set to cycle between 12 hours of light and 12 hours of dark. if the dissolved oxygen concentrations in both flasks are monitored, how will the dissolved oxygen concentration in the flask with algae compare to the control flask?

its 50 miles away from the starting point

step-by-step explanation:

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
