ALL ANSWERED
1.1 Example Questions and Solutions
1.1.1 Level 1: Mathematical Knowledge (4)
Question: What is the value of 7×97 \times 97×9?
Solution: 7×9=637 \times 9 = 637×9=63.
1.1.2 Level 2: Routine Procedures (in a real-life context) (4)
Question: A shop sells a T-shirt for $20. If you buy 3 T-shirts,
what is the total cost?
Solution: 3×$20=$603 \times \$20 = \$603×$20=$60. So, the
total cost is $60.
1.1.3 Level 3: Complex Procedures (in a real-life context) (4)
Question: A car rental company charges a fixed fee of $45 per
day plus $0.25 per kilometer driven. Thandi rents a car for 3
days and drives 360 km. What is her total cost?
Solution (step-by-step):
Daily fee: 3 days×$45=$1353 \text{ days} \times \$45 = \
$1353 days×$45=$135
Distance fee: 360 km×$0.25=$90360 \text{ km} \times \
$0.25 = \$90360 km×$0.25=$90
Total cost: $135+$90=$225\$135 + \$90 = \boxed{\
$225}$135+$90=$225
