Answer:
the final balance as of October 24 is $831.02
Step-by-step explanation:
1. We use a formulae to calculate the final balance as of October 24
2. Bf = I - E + Bi
Where Bf- final balance, Bi- initial balance, I- income, E- expenses
3. Let's get the income
Pay check; 7.25 ×40 × 2 weeks= 580 .
Taxes; 7.65% of 580= 44.37
12% of 580 = 69.6
8.75% of 580 = 50.75
Total taxes= 164.72
Income = 580 - 164.72
= $ 415.28
4. Let get the expenses
One of the sales tax is 6% which will give 1.06 the price of the item. The other expense has no tax. So expenses= 1.06 ×78.54 + 43.9= $ 127.153
Bi = initial balance = $ 542.89
Using the formulae
Bf = I - E + Bi
Final balance= 415.28- 127.1524 + 542.89
=$831.02
Therefore the final balance as of October 24 is $831.02
Answer:
n(n+1)(n+5)/3
Step-by-step explanation:
there is no value, as we don't know n.
but we can create a summary formula/ function definition :
this is the sum for k = 1 to n of k×(k+3)
k×(k+3) = k² + 3k
so, the overall sum splits into the sum of k² for k=1 to n, and the sum of 3k for k=1 to n.
and the sum of 3k is 3 times the sum of k for k=1 to n.
Σk² for k=1 to n = [n(n+1)(2n+1)]/6
Σk for k=1 to n = n(n+1)/2
3×Σk for k=1 to n = 3×n(n+1)/2
so, we have a function formula
n(n+1)(2n+1)/6 + 3n(n+1)/2 = n(n+1)(2n+1)/6 + 9n(n+1)/6 =
= n(n+1)(2n+1+9)/6 = n(n+1)(2n+10)/6 = n(n+1)(n+5)/3
Answer:
im pretty sure its 20%
Step-by-step explanation:
Answer: $16.15
Explanation:
Discount = 10% x $8.50 = 0.1 x $8.50 = $0.85
Price after discount = $8.50 - $0.85 = $7.65
Total Amount = $8.50 + $7.65 = $16.15
It’ll be the one on the far right last one ;)
