What is Savings?</h3>
Saving is the portion of income not spent on current expenditures. In other words, it is the money set aside for future use and not spent immediately.
Here, cost of mattress = $ 1399
cost of EMI = $ 78
Duration of EMI = 18 months
Total payable amount = 18 X 78
= $ 1404
Current account balance = $ 250
Per month savings = $ 50
Duration at which total balance is equivalent to payable amount
= (1404 - 250)/50
= 1154/50
= 23.08
Thus, At least 24 times he need to deposit $ 50 to paying off his total purchase.

Answer:
Expected value =0.9
Standard deviation = 0.4359
Step-by-step explanation:
Let's use the formula to find expected value or mean.
Expected value =Σ x *P(x)
x 0 1 2
P(x) ) .15 .8 .05
So, expected value = (0)(0.15) +1(0.8)+2(0.05)
= 0 +0.8 +0.1
=0.9
Expected value =0.9
Now, let's find standard deviation
x
0 =0.1215
1 =0.008
2 =0.0605
Now, add the last column together and then take square root to find standard deviation.
Standard deviation of the distribution =
Simplify it, so standard deviation =0.4358898...
Round the answer to nearest four decimal places
Standard deviation = 0.4359
