The markup on a restaurant mean is 250%. A meal costs $7.25 to produce. How much will the customer be charged, after markup and 5% GST are applied?

7.30 times 250% = 18.25

2.5 * 7.25 = $18.125

18.125 * 1.05 = ?

I got $19.03.

Please check your figures or ask your teacher for clarification.

ok! thanks a lot.

You're welcome.

To calculate the final price the customer will be charged, you need to first calculate the markup price, and then add the Goods and Services Tax (GST) on top.

Step 1: Calculate the markup price:
The markup is given as 250%, which means the price is increased by 250% of its cost.
To find the markup amount, multiply the meal cost by the markup percentage:
Markup = Meal cost * Markup percentage

In this case:
Markup = $7.25 * 250% = $7.25 * 2.50 = $18.125

Step 2: Add GST:
To include the GST, calculate 5% of the total markup price and add it to the markup price:
GST = Markup price * GST percentage

In this case:
GST = $18.125 * 5% = $18.125 * 0.05 = $0.90625

Step 3: Calculate the final price:
Add the markup price and the GST to get the final price:
Final price = Markup price + GST

In this case:
Final price = $18.125 + $0.90625 = $19.03125

Therefore, the customer will be charged $19.03125, which can be rounded to $19.03 after markup and 5% GST are applied.

but the answer should be $ 26. 65 !
