Answer:
face mask cost 10 pesos each
face shield cost 50 pesos each
Step-by-step explanation:
if a pair of 1 mask and 1 face shield = 60
then 5 pairs of mask and face shield = 300
and nicole paid 330 for 8 mask and 5 face shields, then there is 30 pesos remaining and 3 mask because we only have 5 pairs. therefore 30÷3=10 for the remaining masks. and if a pair of 1 mask and 1 face shield = 60 and 1 mask is 10 pesos then the face shield is 50 pesos.
Computation:
60×5=300 (5pairs of mask and shield)
330-300=30
30÷3=10 ( cost of face mask)
60-10= 50 (cost of face shield)
checking:
10×8= 80 (total cost of 8 facemasks)
50×5=250 (total cost of 5 faceshields)
80+250=330 (total cost of 8 mask and 5 face shields)
