The price of a cup of coffee was $2.15 yesterday. Today, the price rose $2.30. Find the percentage increase round your answer to the nearest tenth of a percent.

7%

Step-by-step explanation:

First, you find the difference between $2.30 and $2.15 to get the amount of change between the two numbers. We get $0.15, so we know that the change was 15 cents more. Next, we find the percent that 25 cents is to $2.15. You get 0.06976... and we can round it to the nearest tenth, which is 0.06. Then you convert that to a percent and you get 7% :)

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
