Final answer:
Josh needs 7 more discs to have a total of 50 discs in his entertainment center. He has 7 fewer discs compared to having 50 discs. The total number of discs Josh can store in his entertainment center is 50.
Step-by-step explanation:
a) To find out how many more discs Josh needs to have 50 discs, we subtract the number of discs he already has from 50: 50 - 43 = 7 more discs.
b) To find out how many fewer discs Josh has compared to having 50 discs, we subtract 43 from 50: 50 - 43 = 7 fewer discs.
c) The total number of discs Josh can store in his entertainment center is 50.
d) To find out how many discs Josh needs to give away to have 50 discs, we subtract 50 from the number of discs he already has: 43 - 50 = 7 discs need to be given away.
