Jermaine had dinner at his favorite restaurant. It the sales tax rate is 4% & the sales tax on the meal was $1.25, what was the total cost of the meal, including sales tax and a 15% tip
TAX: $1.25
RATE: 0.04
TIP: 0.15
TOTAL = MEAL + TIP
MEAL = TAX/RATE = $1.25/0.04 = $31.25
TIP = MEAL*TIP PERCENTAGE = $31.25*0.15 = $4.69
TOTAL = MEAL + TIP = $31.25 + $4.69 = $35.94
(or, instead of adding the tip to the meal, you could multiply the meal by 1.15, which is like multiplying the meal by 0.15 and then adding that to the meal to get the tip + meal)
0.04x = 1.25
x = 1.25/0.04
x = 31.25
31.25 * 1.15 = ??
where did you get the 1.15, do u mean 1.25?
1.15 is the amount of the tip plus the meal.
You could also do it this way.
31.25 * 0.15 = 4.69
31.25 + 4.69 = ?
37.19
To find the total cost of the meal, including sales tax and a 15% tip, we need to follow these steps:
Step 1: Determine the cost of the meal before adding sales tax and tip. Let's call this amount X.
Step 2: Calculate the sales tax amount by multiplying the sales tax rate (4%) by the cost of the meal before tax (X). This will give us the sales tax amount.
Step 3: Calculate the total cost of the meal after adding sales tax by adding the cost of the meal before tax (X) and the sales tax amount.
Step 4: Calculate the tip amount by multiplying the cost of the meal before tax (X) by the tip rate (15%).
Step 5: Determine the total cost of the meal, including sales tax and the tip, by adding the cost of the meal before tax (X), the sales tax amount, and the tip amount.
Now, let's break down the problem and solve it step-by-step:
Step 1: Determine the cost of the meal before adding sales tax and tip. Let's call this amount X.
Step 2: Calculate the sales tax amount by multiplying the sales tax rate (4%) by the cost of the meal before tax (X). This will give us the sales tax amount:
Sales Tax Amount = X * 0.04
Step 3: Calculate the total cost of the meal after adding sales tax by adding the cost of the meal before tax (X) and the sales tax amount:
Total Cost with Sales Tax = X + (X * 0.04)
Step 4: Calculate the tip amount by multiplying the cost of the meal before tax (X) by the tip rate (15%):
Tip Amount = X * 0.15
Step 5: Determine the total cost of the meal, including sales tax and the tip, by adding the cost of the meal before tax (X), the sales tax amount, and the tip amount:
Total Cost of the Meal = X + (X * 0.04) + (X * 0.15)
Now we know that the sales tax on the meal was $1.25, so we can set up the equation:
X * 0.04 = 1.25
Solving the equation for X, we get:
X = 1.25 / 0.04
X = 31.25
Now, substituting the value of X back into the formula for the total cost of the meal:
Total Cost of the Meal = 31.25 + (31.25 * 0.04) + (31.25 * 0.15)
Total Cost of the Meal = 31.25 + 1.25 + 4.6875
Total Cost of the Meal = $37.1875
Therefore, the total cost of the meal, including sales tax and a 15% tip, is $37.1875.
