Answer:
1. 50 pupils
2. ₱153
3. ₱7500
4. ₱ 3600
5.12 mistakes
Step-by-step explanation:
1.B = P/R
B = 8/16%
B = 8/.16
B = 0.5
B= 50 pupils
2. P= BXR
P=180x15%
P=27
180-27(discount) = ₱153
3. 100%-20%= 80%
B=P/R
B=6000/80%
B= 6000/.80
B=₱7500
4. P= BXR
P=4500x20%
P=4500x.20
P= 900
4500-900(discount) = ₱3600
5. P= BXP
P=60x20%
P=60x.20
P= 12 mistakes
