Step 15: 7770 + 555 = 8325
Step 16: 8325 + 555 = 8880
Step 17: 8880 + 555 = 9435
Step 18: 9435 + 555 = 9990
Step 19: 9990 + 555 = 10545
Step 20: 10545 + 555 = 11100
Step 21: 11100 + 555 = 11655
Step 22: 11655 + 555 = 12210
Step 23: 12210 + 555 = 12765
Step 24: 12765 + 555 = 13320
Step 25: 13320 + 555 = 13875
Step 26: 13875 + 555 = 14430
Step 27: 14430 + 555 = 14985
Step 28: 14985 + 555 = 15540
Step 29: 15540 + 555 = 16095
Step 30: 16095 + 555 = 16650
Step 31: 16650 + 555 = 17205
Step 32: 17205 + 555 = 17760
Step 33: 17760 + 555 = 18315
Step 34: 18315 + 555 = 18870
Step 35: 18870 + 555 = 19425
Step 36: 19425 + 555 = 19980
Step 37: 19980 + 555 = 20535
Step 38: 20535 + 555 = 21090
Step 39: 21090 + 555 = 21645
Step 40: 21645 + 555 = 22200
Step 41: 22200 + 555 = 22755
Step 42: 22755 + 555 = 23310
Step 43: 23310 + 555 = 23865
Step 44: 23865 + 555 = 24420
