Q + r + s.....q = 46, s = 54
46 + r + 54
100 + r <==
Answer:
3x-2
Step-by-step explanation:
Initial balance : 463.76
refunds : 12.56 + 52.11 + 26.03 = 90.70
sales : 101.32 + 10.98 = 112.30
463.76 - 90.70 + 112.30 = 485.36 is the correct balance
so there is a (511.39 - 485.36) = 26.03 difference
so the mistake made was instead of subtracting the 26.03 refund, she added it as a sale
