Answer:
4 copies
Step-by-step explanation:
After yesterday's sales, 1/3 of the original supply remained. After today's sales, 1/5 of that value remain. So the remaining number is ...
60·(1/3)(1/5) = 60/15 = 4
10^ 7 = 10,000,000 which is 10 million
10^ 8 is 100 million
10^8 is closer, it is only 130 million away while 10^7 is 220 million away
