<h3>What is the percentage?</h3>
The quantity of anything is stated as though it were a fraction of a hundred.
Jason purchased a pack of game cards that were on sale for 13% off.
The sales tax in his county is 8%.
Let y represent the original price of the cards.
Then the expression can be used to determine the final cost of the cards will be
⇒ y (1 - 0.13) (1 + 0.08)

Answer:
1. 516 ppm; 2. 561 ppm
Step-by-step explanation:
1. CO₂ increase at old rate
Time = 2100 - 2010 = 90 years
Increase in CO₂ = 90 yr × (1.4 ppm/1 yr) = 126 ppm
CO₂ in 2010 = 390 + 126 = 516 ppm
At the old rate, the CO₂ concentration in 2100 will be 516 ppm.
2. CO₂ increase at new rate
Time = 2100 - 2010 = 90 years
Increase in CO₂ = 90 yr × (1.9 ppm/1 yr) = 171 ppm
CO₂ in 2010 = 390 + 171 = 561 ppm
At the new rate, the CO₂ concentration in 2100 will be 561 ppm.
