Answer:

Step-by-step explanation:

Given the equation y = 0.18x, to solve for x, we will make the variable x as the subject of the formula from the equation given.

From the equation y = 0.18x

Divide both sides by the coefficient of x i.e 0.18

y/0.18 = 0.18x/0.18

y/0.18 = x

Hence the function of the variable x = y/0.18

b) Given the amount of the bill as y and x is the tip in dollars.

Given  y = $4.95, we are to substitute the value of y = $4.95 into the resulting function in (a) to get x as shown;

Since x = y/0.18

x = $4.95/0.18

x = $27.5

Hence the bill is  $27.5
