Aprinter is printing photos. for every 12
photos, the printer takes 3
minutes.
complete the table below showing the number of photos and the time it takes to print them.

See below  

Step-by-step explanation:

The printer prints 12 photos/3 min = 4 photos/1 min.  

The formula is n = 4t

Number of photos  4 12  24  32  36

Time/min                  1   3    6    8    9

1) a: [$]75 + [$]0.20x = ƒ(m) b: [$]0.35x = ƒ(m)the 75 is how much you automatically pay and the .2x and .35x is how much you would pay per mile (the variable can be changed to your liking). ƒ(m) is the total cost. 2) set your equations to equal each other.75 + .2x = .35xsolve.move the .2x over by subtracting it from both sides. 75 = .15xget x by itself by dividing both sides by 0.15.500 = xit would take 500 miles for plan a and b to be equal in cost.
