Determine whether y varies directly with x. If so, find the constant of variation k.

-5y=-2x divide both sides by -5

y=2.5x

So this is a direct variation with a constant of 2.5

A computer store changed the price of a laptop. It was originally $900, but now it is $1,100.Find the percent of change

tigry1 [53]

Answer:

The percent of change is 22.22%.

Step-by-step explanation:

You can calculate the percent of change by subtracting the original number from the final number and dividing that by the original number. Then, you have to multiply the result for 100:

percent of change=((1,100-900)/900)*100

percent of change=(200/900)*100

percent of change=22.22%

According to this, the answer is that the percent of change is 22.22%.
