$4825.70
Step-by-step explanation:
Cost for Fans: 4 x 675 = $2700
Cost for Lamps: 2 x 110 = $220
Cost for Switches: 5 x 41 = $205
Cost for Tubes: 6 x 135 = $810
Cost for Electric Wire: 230 x 2.50 = $575
Total cost: 2700 + 220 + 205 + 810 + 575 = $4510
Tax: Total cost x Tax rate = 4510 x 0.07 = $315.70
Total paid: Total cost + Tax = 4510 + 315.70 = $4825.70
Answer:
for
Step-by-step explanation:
Given
-- First Term
--- half common difference
Required
Find the recursive rule
First, we calculate the common difference
Multiply through by 2
The second term of the sequence is:
The third term is:
So, we have:
Substitute f(1) for 3
Express 1 as 2 - 1
Substitute n for 2
Similarly:
Substitute f(2) for 11
Express 2 as 3 - 1
Substitute n for 3
Hence, the recursive is:
for
You will have 16 bars left.
12 + 11 + 6 = 29 people like the drinks. So subtract 29 from 50 and you get 21 people who don't like either.
The answer is 666. You can use a calculator for future questions like these :)
