Your house can be painted in a choice of 7 exeterior colors and 15 interior colors. Assuming that you choose only 1 color for the exterior and 1 color for the interior, how many different ways of painting your house is there???
I made up a list of 7 colors, then a list of 15 different colors
I used each color once.. what i came up with was just 15x7=105..
am i doing this right? is there another method to solving the problem? Thanks..

No you are doing it fine! For each of the 7 colors there are 15 other possibilities. So, 7 colors x 15 others = 105 possibilities!
