Answer:
5 erasers.
Step-by-step explanation:
0.35e + 0.15p = 2.80
e + p = 12
e = 12 - p
0.35(12 - p) + 0.15p = 2.80
4.2 - 0.35p + 0.15p = 2.80
4.2 - 0.2p = 2.80
-0.2p = -1.4
-0.2p/-0.2p = -1.4/-0.2
p = 7
e = 12 - 7
e = 5
Answer: 3/4 x 48
3 x 12
= 36
Got 12 by reducing the numbers with the Greatest Common Factor (GCF) 4
