heidi left a 25% tip of $9.00 dollars on a meal. what was the cost of the meal before the tip? what was the total cost of the meal before the tip?

0.25x = 9

x = 9/0.25
x = ?

To find the cost of the meal before the tip, we need to determine what percentage of the total cost the $9.00 tip represents. Since Heidi left a 25% tip, we can set up the equation:

25% of the meal cost = $9.00

To solve for the meal cost, we need to divide $9.00 by 25% (or 0.25 as a decimal):

Meal cost = $9.00 / 0.25 = $<<9/0.25=36.00>>36.00

Therefore, the cost of the meal before the tip was $36.00.

To find the total cost of the meal before the tip, we add the tip amount ($9.00) to the meal cost:

Total cost of the meal before the tip = Meal cost + Tip amount
Total cost of the meal before the tip = $36.00 + $9.00 = $45.00

Therefore, the total cost of the meal before the tip was $45.00.
