The number of permutations of 8 people taken 6 at a time is given by:
Irma’s annual income has the delivery fees already taken out. earnings based on salary and commission is higher becuase fees have not been taken out
The total cost for plumber number 1 expressed as a function of x is
c1(x)=45x+90
That is, the charge per hour times the number of hours plus the fixed charge for a visit.
Using the same pattern, write the function for the second plumber. Then set the two functions equal to each other and solve for
Box A : 5 x 2 x 3 = 30 cubic cm
Box B: 2 x 2 x 6 = 24 cubic cm
Box C: 6 x 3 x 2 = 30 cubic cm
Answer:
x=24
