The Jacksonville Walmart normally gets 120 customer complaints per day. That number increases by 1/3rd when they're short-staffed and this increases by another 20% when the self-checkout is broken. If the store was short-staffed and the self-checkout was broken for 3 days, how many complaints does the store get? Think carefully first, then make a decision:
First find the number of complaints per day when the store is short - staffed: 120 complaints / day * 4 / 3 = 160 complaints / day. Then find the number of complaints per day when the self - checkout is broken and they're short - staffed: 160 complaints / day * 1.2 = 192 complaints / day. Then multiply the number of complaints per day by the number of days to find the total number of complaints: 192 complaints / day * 3 days = 576 complaints. So, the answer is 576.
