Final answer:
The sales team at K-Mart needs to sell at least 68 television sets in May, which represents a 28% increase over the 53 sets sold in April.
Step-by-step explanation:
To calculate the number of television sets the sales team at K-Mart must sell in May to receive a bonus, we start with the number of television sets sold in April, which is 53. The manager has set a target increase of 28% for May. To find the increased number of television sets, we calculate 28% of 53, which is 0.28 × 53.
0.28 × 53 = 14.84
Since it is not possible to sell a fraction of a television set, we round up to the nearest whole number, which is 15. To find the total number of TVs that need to be sold in May to receive the bonus, we add the 15 additional TVs to the original 53 TVs sold in April.
53 + 15 = 68
Therefore, the sales team must sell at least 68 television sets in May to receive the bonus.
