Miss Lee spent $840 on a vacation. She spent two thirds of the amount on a train ticket and half of the remaining amount on food. How much did she spend on the ticket and food all together?

(2/3) * 840 = 560

(840 - 560) * (1/2) = ?

To find out how much Miss Lee spent on the ticket and food together, we need to follow a step-by-step process.

Step 1: Calculate the amount Miss Lee spent on the train ticket.
Since she spent two-thirds of the total amount on the ticket, we can find this amount by multiplying 840 by 2/3:
Ticket amount = 840 * 2/3 = $560

Step 2: Calculate the remaining amount after purchasing the ticket.
To find the remaining amount, we subtract the ticket amount from the total amount spent:
Remaining amount = Total amount - Ticket amount = $840 - $560 = $280

Step 3: Calculate the amount Miss Lee spent on food.
Since she spent half of the remaining amount on food, we can find this amount by multiplying the remaining amount by 1/2:
Food amount = Remaining amount * 1/2 = $280 * 1/2 = $140

Step 4: Calculate the total amount spent on the ticket and food.
To find the total amount spent on the ticket and food together, we add the ticket amount and the food amount:
Total amount = Ticket amount + Food amount = $560 + $140 = $700

Therefore, Miss Lee spent $700 on the ticket and food all together.
