Answer:
6 phones and 18 accessories
Step-by-step explanation:
12P + 3.50A = 135
A = 12 + P
12P + 3.50(12 + P) = 135,
12P + 42 +3.50P = 135
15.50P = 93
P = 6 phones
A = 12 + 6 = 18 accessories
The easiest way to find that answer is to look at the solution that I just gave you for the same ball traveling at 30 M/Sec, and just substitute 20 in place of 30 in that solution.
