Add all the clay together and divide it by 5 so the answer is 13
2:10=>3:10, was 1 hour
3:10=> 3:22, were 12 minutes
the play last 1 hour 12 minutes (or 60+12= 72 minutes).
Mod 8, the sequence repeats after 12 terms:
1 3 4 7 3 2 5 7 4 3 7 2
Thus the 100th term, mod 8, will be the 4th term of this sequence: 7
10 × $150 = $1500
88 × $85.50 = $7524
1500 + 7524 = $9024 a day.
9024 × 6 = $54,144 (the answer)
Hope this helps!
