heidi left a 12% tip of $2.28 on a meal.What was the cost of the meal before the tip. What was the total of the meal including the tip

Let X be the cost before tip.

0.12 X = 2.28
X = $19.00
Add the tip to that for the total cost.

To find the cost of the meal before the tip, we can first calculate the tip amount and then use that to subtract from the total cost. Here are the steps:

Step 1: Calculate the tip amount
We know that the tip is 12% of the meal cost. Let's represent the meal cost as "x". We can calculate the tip amount (t) using the formula t = x * 12% = 0.12x. We are given that the tip amount is $2.28, so we can set up an equation: 0.12x = $2.28.

Step 2: Solve for x
To solve for x, divide both sides of the equation by 0.12:
x = $2.28 / 0.12 = $19

Therefore, the cost of the meal before the tip is $19.

Step 3: Calculate the total cost of the meal including the tip
To find the total cost of the meal, we need to add the cost of the meal before the tip and the tip amount. In this case, the total cost (T) is given by the formula T = x + t = $19 + $2.28 = $21.28.

Therefore, the total cost of the meal including the tip is $21.28.
