Learning Task 3:
Solutions:
1. Given: ₱35.50 - cost of lunch per week
15.5 - number of weeks
Find the total cost of the lunches by multiplying the cost per week with the total number of weeks.
Total Cost = cost of lunch per week x number of weeks
Total Cost = ₱35.50 x 15.5
Total Cost = ₱550.25
Therefore, the total cost of the lunches for 15.5 weeks is ₱550.25
2. Given: ₱71.75 - Lorna's earning per hour
21 - number of hours Lorna had worked
Find Lorna's total earning by multiplying her earning per hour with the total number of hours she had worked.
Total Earning = earning per hour x total number of hours
Total Earning = ₱71.75 x 21
Total Earning = ₱1,506.75
Therefore, Lorna have earned ₱1,506.75.
3. Given: ₱1,023,660 - car loan costs
60 - number of months that the car will be paid
Find the monthly payment by dividing the car loan costs with the number of months that the car will be paid.
Monthly Payment = ₱1,023,660 ÷ 60
Monthly Payment = ₱17,061
Therefore, Paul's father will pay ₱17,061 monthly for his car.
4. Given: 1.28 m - length of the ribbon
2.74 m - the difference between the length of the ribbon and rope
Find the length of the rope by adding the length of the ribbon and the difference between the two.
Length of the Rope = 1.28 m + 2.74 m
Length of the Rope = 4.02 m
Therefore, the rope is 4.02 m long.
5. Given: 5.2 liters - volume of the pail
3.9 liters - the difference between the volume of the pail and bottle
Find the volume of the bottle by subtracting the volume of the pail and the difference between the volume of the two.
Volume of the Bottle = Volume of the Pail - the difference between the volume of the pail and bottle
Volume of the Bottle = 5.2 liters - 3.9 liters
Volume of the Bottle = 1.3 liters
Therefore, the volume of the bottle is 1.3 liters.
