A store offers a 14% discount on a DVD. If the cost is discounted by $4.90, what is the original cost of the DVD?

35

Step-by-step explanation:

Let's call the original price X

14% of x is equal to $4.90 to calculate 100% of the price we multiply 100 with 4.9 then divide it with 14

4.9 × 100 ÷ 14 = 35

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
