Final answer:
In order to determine if the cashier's estimate is correct, we need to add up the total amount of money made from selling the t-shirts. Prior to the event, £89.80 worth of t-shirts were sold. The cashier's estimate of the most popular t-shirt design making £300 when rounded to the nearest hundred is not correct.
Step-by-step explanation:
In order to determine if the cashier's estimate is correct, we need to add up the total amount of money made from selling the t-shirts. Prior to the event, £89.80 worth of t-shirts were sold. During the concert, £30.65 worth of t-shirts were sold. After the event, £180.50 worth of t-shirts were sold. When we add these amounts together, we get £301.95, which is more than the cashier's estimate of £300 when rounded to the nearest hundred.
