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?
The supermarket has 15 cases * 24 tins/case = 
<gadget id="calculator">15*24</gadget>
<output>360</output>
360 tins of beans delivered to them.
There are 360 tins * 0.05 = 
<gadget id="calculator">360*0.05</gadget>
<output>18</output>
18 tins that are damaged and unsellable.
So in the end, there are 360 tins - 18 tins = 
<gadget id="calculator">360-18</gadget>
<output>342</output>
342 tins of beans that are left.
