QUESTIONS!!
1.How much would it cost to carpet a room 4m by 3m at €9 per square metre?
2. A television set can be purchased for € 299 cash or a deposit of €50 and 12 monthly payments of €25. How much do I save by paying cash?
3. How many thousands in a million?
4. A distance of 8km is represented on a map by a line 8cm long. The scale is 1cm to ? km.
4*3*9 = 108
50 + 12*25 = 350
350 - 299 = 51
10^6/10^3 = 10^3 = 1000
8cm / 8 km
so
1 cm / 1 km
1. To calculate the cost of carpeting a room, you need to multiply the area of the room by the price per square meter. In this case, the room is 4 meters by 3 meters, giving an area of 12 square meters. The price per square meter is €9. So, to calculate the total cost, you can use the formula:
Cost = Area * Price per square meter
Cost = 12 square meters * €9
Cost = €108
Therefore, it would cost €108 to carpet the room.
2. To determine how much you save by paying cash for the television set, you need to compare the total cost of paying cash with the total cost of the deposit and monthly payments.
Option 1: Paying cash for €299.
Option 2: Making a deposit of €50 and 12 monthly payments of €25.
To calculate the total cost for Option 2, add the deposit to the total of the monthly payments:
Total cost = Deposit + (Monthly payment * Number of payments)
Total cost = €50 + (€25 * 12)
Total cost = €50 + €300
Total cost = €350
To calculate the savings, subtract the total cost of cash payment from the total cost of the installment plan:
Savings = Total cost (Cash) - Total cost (Installment plan)
Savings = €299 - €350
Savings = -€51
Therefore, you would save €51 by paying cash.
3. To determine how many thousands are in a million, you need to divide one million by one thousand:
Million / Thousand = 1,000,000 / 1,000
This calculation gives you the answer:
1,000,000 / 1,000 = 1,000
Therefore, there are 1,000 thousands in a million.
4. To find the scale of the map representing a distance, divide the actual distance by the length of the line on the map:
Actual distance / Map distance = Scale
In this case, the actual distance is 8 km, and the length of the line on the map is 8 cm:
8 km / 8 cm = Scale
The scale can be represented as 1 cm to x km:
1 cm / x km = 8 cm / 8 km
Cross-multiplying, you get:
1 cm * 8 km = 8 cm * x km
8 km = x km
Therefore, the scale is 1 cm to 1 km.
