Answer:

300 more times

Step-by-step explanation:

It is mentioned that a 12 years old blinks 150 times in 15 mins.

We know that 15 times 4 is 60 which results in 600 times in 60 minutes.

Again, an adult blinks 450 times in 30 minutes.

We know that 450 times 2 is 900

Next, subtract 600 from 900

equals to 300 times more

Jason works at least 5 hours but not more than 10. He earns $15.00 per hour. The function f(x) = 15t represents the money he ear
frosja888 [35]

Answer:

Step-by-step explanation:

The amount of money that Jason earns is dependent on the amount of time, t in hours that he works

The function f(x) = 15t represents the money he earns for working t hours. Therefore, the dependent variable is f(x) and the independent variable is t

Jason works at least 5 hours but not more than 10. This means that The minimum amount that he can earn is 15×5 = $75

The maximum amount that he can earn is 15×10 = $150

The practical domain is all possible values for t. It becomes

5 lesser than or equal to t lesser than or equal to 10

The practical range is all possible values for f(x). It becomes

75 lesser than or equal to f(x) lesser than or equal to 150
