Answer:

1. P 3400.00

2. 45 minutes

3. 120:480:600 faceshields each

Step-by-step explanation:

used direct proportion

1. 5:850 , 20:N

5N = 850 x20

5 5

N= P 3400

2. use inverse proportion

30:60 , 40: N

60:40, 30:N

40N =60x30

40 40

N = 45 minutes

3. use partitive proportion

1N+4N+5N=1200

10N = 1200

10 10

N = 120

1(120): 4(120):5(120)

=120:480:600 faceshields
