Answer = 4.73
Example 2.2(2.15) = 4.73
The correct Option is A. $6.80
Explanation:
For first 16 kWh => $2
For next (80 - 16 = 64 kWh) => 64 * $0.075 = $4.8
Add both of them:
$2 + $4.8 = $6.80 (Option A)
For this kind of questions, we need to check the problem carefully...
So there are 45 pupils all in all, and 9 of them gave their sweets away... Therefore, the rest of pupils would be 45-9= 36.
These 36 pupils then got 2 more sweets than they originally have. We can then set x as the number of candies they originally got.
We will then create an equality, since the total number of candies is the same in the 2 scenarios: a) all 45 pupils have candies b) 36 pupils get 2 more
45x = 36(x+2)
45x = 36x + 72
45x - 36x = 72
9x = 72
x = 8 candies
Total number of candies would then be 45x which is 45(8) = 360 candies.

Answer:
Slope of the line perpendicular to the given line = 
Step-by-step explanation:
If two are lines are perpendicular to each other,
the product of their slopes = - 1 .
That is ,
Slope of the given line :
Hence slope of the line perpendicular to it :
