Well the Regular Price is the price before the sale was added. So here's the work that I would put in and in the end, just divide by (1 - 0.38).
Price x (1 - 0.38) = Sale Price (529)
Price x 0.62 = 529
Price = 529 / 0.62 = 853.23
$853.23 was the Regular Price
This problem is based on the Greenhouse effect.
CO2 is one of the Greenhouse gases.
Gasoline and diesel cars gasoline burns fossil fuel and produce a lot of CO2 increasing the Greenhouse effect.
The sentences of the statement for the this case may be ordered to describe very well what happens with the fossil fuels and their effect in the planet.
This is the right order:
1) fossil fuels burned to run vehicles release co2
<span>2) CO2
traps heat and warms the atmosphere.
</span>
<span>3) The global surface temperature increases
4) ice and snow in
polar regions melts.
5)</span><span><span> large amounts of freshwater flow into
