Aling Luz bought yards of linen cloth which cost Php 72.00 per yard. She gave Php 1 000.00 to the cashier. How much change will she ​

Step-by-step explanation:

1.To find the area of the room, you can use the formula for finding the area of a rectangular prism, which is:

Area = Length x Width x Height

In this case, the length is 8 meters, the width is 8 – 2/2 meters, and the height is 5 – 10 meters.

Let’s calculate the area:

Area = 8 meters x (8 – 2/2 meters) x (5 – 10 meters)

Now, simplify the expression inside the parentheses:

Area = 8 meters x (8 – 1 meters) x (-5 meters)

Area = 8 meters x 7 meters x (-5 meters)

Now, multiply the numbers:

Area = 56 square meters x (-5 meters)

Area = -280 square meters

So, the area of the room is -280 square meters. However, a negative area doesn’t make physical sense, so it’s important to double-check the measurements provided for accuracy. It’s possible that there was an error in the measurements given for the room’s dimensions.

2.To find the total kilograms of rice packed by the volunteers, you can simply multiply the number of bags by the amount of rice in each bag.

198 bags x 3 kilograms/bag = 594 kilograms

So, the volunteers packed a total of 594 kilograms of rice.

3.To find out how many tablespoons of melted butter the baker used for 13 kilograms of flour, you can use the given ratio: 3 tablespoons of melted butter for every kilogram of flour.

First, calculate the amount of butter needed for 13 kilograms of flour:

3 tablespoons per kilogram x 13 kilograms = 39 tablespoons

So, the baker used 39 tablespoons of melted butter for 13 kilograms of flour.

4.To find out how much change Aling Luz will have, you need to subtract the total cost of the linen cloth from the amount she gave to the cashier.

Let’s calculate it:

Cost per yard of linen cloth = Php 72.00

Total yards of linen cloth bought = Php 1,000.00

Now, divide the total amount by the cost per yard:

Total cost of the linen cloth = Total yards x Cost per yard

Total cost = 1000 / 72 = 13.89 (rounded to two decimal places)

So, the total cost of the linen cloth is approximately Php 13.89.

Now, subtract the total cost from the amount Aling Luz gave to the cashier:

Change = Amount given – Total cost

Change = Php 1,000.00 – Php 13.89 = Php 986.11

Aling Luz will have Php 986.11 in change.
