A supermarket receives a delivery of 15 cases of tins of beans. Each case contains 24 tins. If 5% of the tins are damaged and thrown away, how many tins of beans are left? Let's answer step by step:
The supermarket has 15 cases × 24 tins / case = 360 tins of beans delivered to them. There are 360 tins × 0.05 = 18 tins that are damaged and unsellable. So in the end, there are 360 tins - 18 tins = 342 tins of beans that are left. The answer: 342.
