Last week John made/has $50.00 from playing the lottery. This week he lost $25.00 playing the same lottery game. What is his percent of change between last week 20. and this week? First find the difference, the amount of change in John's money, then find the percent of change for how much money John now has.

He lost 50% and he was 25 left I think

Step-by-step explanation:

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.
