Answer:
$1.09
Step-by-step explanation:
16*0.09 = 1.44, 16 + 1.44 = 17.44 (Henry's total cost)
17*0.09 = 1.53, 17 + 1.53 = 18.53 (Ella's total cost)
To find the difference we subtract 18.53-17.44 = 1.09 and so the difference including tax is $1.09
Answer:
C
Opening the bracket is the first order in solving arithmetic from BODMAS but to do that in this case we need to add 4^3 and 9 which first requires us to find 4^3
The slopes of perpendicular lines are negative reciprocals.
If one line has a slope of 1/6, then the negative reciprocal would be -6/1 which is simplifies as -6.
The answer is C.
