If Tom has 3 different sweaters, and 5 different pairs of pants, how many different combinations could he wear?
Vladimir [108]
Check the tree diagram in the picture.

Similarly if we picked P2, P3, P4 or P5 we would have 3 combinations per each.

In total we have 5*3=15 different combinations.

Kipish [7]

Answer:

After 15 years the use of said machine is no longer profitable

Step-by-step explanation:

it should be used, as long as the money generated is not smaller as the costs generated. By setting both formulas equal (calculating the x value for when they are equal) you get x = 15 and x = -2.5(which doesnt make sense in this context).
