We need to find the function value of floor function
Floor function comes under integer functions. we have floor and ceiling function.
Ceiling function gives the least integer value greater than or equal to x.
Floor function gives the greatest integer values less than or equal to x.
For example Celing(3.8) = 4
floor (3.8)= 3
Like that floor f(-0.75) = -1
greatest integer value less than -0.75 is -1
First put them in order: 12, 12.2, 12.3, 12.6, 12.8, 12.8, 13.5, 13.9, 14, 14.2. The minimum (the lowest) is 12. The median (the middle number) is 12.8. The third quartlile is approximately 13.9. The first quartile is 12.25. He lied about the first quartile :)
Answer:
Step-by-step explanation:
Given
--- first discount
--- second discount
Required
Determine the amount paid
First, we add the total discount:
If she got a discount of 40%, then she paid 60% (i.e. 100% - 40%)
So:
Calculate the sales tax
By putting the x on one side then solve it
