Josh worked 50 hours frank worked 50 hours less and twice as many hours as josh did. How many hours did frank work

50 hours

Step-by-step explanation:

Josh = 50 hours

frank worked 50 hours less and twice as many hours as josh did.

Frank = 2(Josh) - 50 hours

= 2(50 hours) - 50 hours

= 100 hours - 50 hours

= 50 hours

Therefore, Frank worked for 50 hours

This is a perfect example of exponential decay. In this case the growth factor should be represented by a fraction, and it is! This forest, starting out with apparently ( 800? ) pine trees, has a disease spreading, which kills 1 / 4th of each of the pine trees yearly. Therefore, the pine trees remaining should be 3 / 4.

Respectively 3 / 4 should be the growth factor, starting with 800 pine trees - the start value. This can be represented as such,

- where a = start value, b = growth factor, t = time ( variable quantity )

____

Thus, the function can model this problem. The forest after t years should have P( t ) number of pine trees remaining.
