Answer:
It will take Jack 16 weeks to save enough money to buy the computer.
Step-by-step explanation:
To find the answer, we can divide the cost of the computer ($960) by the amount of money Jack is saving per week ($60), which leaves us with the number of weeks it will take him to save enough money to buy the computer (16).
To check this math, we can multiply the amount of money Jack is saving per week ($60) by the number of weeks it will take him to save enough money to buy the computer (16), which gives us the cost of the computer ($960) and tells us that this answer is correct.

Answer:
$13.67
Step-by-step explanation:
Let's say that CD= c and DVDs= d. Four CDs and 4 DVDs cost $164, so the equation will be:
i. 4c + 4d= 164
The cost of the 4 CDs is half the cost of the 4 DVDs, to put into an equation it will be:
ii. 4c= 0.5(4d)
4c= 2d
d= 2c
Then we can substitute the second equation (ii) into the first equation (i). The calculation will be:
4c + 4d= 164
4c + 4(2c)= 164
4c+ 8c= 164
12c= 164
c=13.67
The cost for each CD is $13.67
0.3 or 30%. The probability that Ace pick a banana from a basket that content others fruits is 0.3.
The key to solve this problem is using the equation of probability 
where n(A) the numbers of favorables outcomes and n the numbers of possible outcomes.
There are in the basket 10 fruits in total (3 bananas + 4 apples + 3 oranges = 10fruits). Then, extract a fruit can occur in 10 ways, this is n. There is only 3 bananas in the basket, so the fruit that ACE will pick be a banana can occur in 3 ways out of 10, so 3 is n(A).
Solving the equation:
