In 2013, selected automobiles had an average cost of $16,000. The average cost of those same automobiles is now $20,000. What was the rate of increase for these automobiles between the two time periods

25%

Step-by-step explanation:

The average cost of the automobile in 2013 is $16,000

The present cost now is $20,000

Therefore the rate of increase between the two automobiles can be calculated as follows

= 20,000-16,000/16,000

= 4,000/16,000

= 0.25×100

= 25%

Hence the rate of increase is 25%

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .

b.an increase in a causes b to decrease
