For her youngest son's birthday party, Mother bought 6 1/4 kg of hotdogs and 5 1/3 dozens of bread rolls. Hotdogs cost ₱160.00 per kilogram and a dozen of bread rolls costs ₱25.00. How much did she spend in all?
Answer (1)
To find out how much Mother spent in total for the birthday party, we need to calculate the cost of the hotdogs and the bread rolls separately, and then add those amounts together.
Step 1: Calculating the cost of hotdogs
Mother bought 6 4 1 kg of hotdogs. First, convert the mixed number to an improper fraction:
6 4 1 = 4 25
Each kilogram of hotdogs costs ₱160.00, so the cost of the hotdogs is:
Cost of hotdogs = 4 25 × 160
First, multiply 25 by 160, then divide by 4:
25 × 160 = 4000
Then divide: 4 4000 = 1000
So, the cost of the hotdogs is ₱1,000.00.
Step 2: Calculating the cost of bread rolls
Mother bought 5 3 1 dozens of bread rolls. Convert the mixed number to an improper fraction:
5 3 1 = 3 16
Each dozen of bread rolls costs ₱25.00, so the cost of the bread rolls is:
Cost of bread rolls = 3 16 × 25
First, multiply 16 by 25, then divide by 3:
16 × 25 = 400
Then divide: 3 400 ≈ 133.33
Since money is generally rounded to the nearest cent, the cost of the bread rolls is approximately ₱133.33.
Step 3: Calculating the total cost
Finally, add the cost of the hotdogs and the cost of the bread rolls to find the total amount spent:
Total cost = 1000 + 133.33 = 1133.33
Therefore, Mother spent a total of approximately ₱1,133.33 on hotdogs and bread rolls for her youngest son's birthday party.
