slega [8]

Answer: There is increase of 4.255 in the amount of carbon in the atmosphere.

Step-by-step explanation:

Since we have given that

Concentration of carbon in Earth's atmosphere in 1800 = 280 ppm

Concentration of carbon in Earth's atmosphere in 2015 = 399 ppm

We need to find the percentage increase in the amount of carbon in the atmosphere.

So, Difference = 399-280 = 119 ppm

so, percentage increase in the amount of carbon is given by

$\dfrac{Difference}{Original}\times 100\\\\=\dfrac{119}{280}\times 100\\\\=\dfrac{11900}{280}\\\\=42.5\%$

Hence, there is increase of 4.255 in the amount of carbon in the atmosphere.

maria [59]

The total cost to stay one night at sleepyhead motel without breakfast = $119

The total cost to stay one night at sleepyhead motel with breakfast = $124

We have to find the difference in the cost for a one night stay with and without breakfast.

Difference = $124 - $119

= $5

Therefore, the difference in the cost for a one night stay with and without breakfast is $5.
