Suppose there are signs on the doors to two rooms. The sign on the first door reads "In this room there is a lady, and in the ot
her one there is a tiger"; and the sign on the second door reads "In one of these rooms, there is a lady, and in one of them there is a tiger." Suppose that you know that one of these signs is true and the other is false. Behind which door is the lady?
The best thing to do is to find the cost of one sweet, and to do this, divide 42 by 7. 42/7= 6 Therefore, one sweet costs 6p. To find the cost of 8 sweets, you've got to multiply 6 by 8, and this gives you 54p. Therefore, 8 sweets cost 54p This is basically just finding unit rate and multiplying. <span>Hope this helps :)</span>
