Ms. hernandez has 17 tomato plants that she wants to plant in rows. she will put 2 plants in some rows and 1 plant in the others. how many different ways can she plant the tomato plants?

You just neeed to figure out the number of ways you can form 17 with the numbers 2 and 1. The easiest way is to write 17 as a function of the number of rows. If there are x rows with two plants and y rows with 1 plant, this equation is valid: 17= 2x + y, from which you can solve for y, y = 17 - 2x. Now you can give different whole values to x, to find the possible solution: x = 1 => y = 17 - 2 = 15. That means 1 row with 2 plants ans 15 rows - with 1 plant; x = 2 => y = 17 - 4 = 13; x = 3 => y = 17 - 6 = 11; x= 4 => y = 17 - 8 = 9; x = 5 => y = 17 - 10 = 7; x = 6 => y = 17 - 12 = 5; x = 7 => y = 17 - 14 = 3; x = 8 => y = 17 - 16 = 1. You cannot use x = 9, because that gives 2x = 18 and there are only 17 plants. So you have 8 different ways to plant the tomato plants using only 2 plants sin som rows and 1 plant in others (x from 1 to 8).

If your asking how much altogether for 12 performance the answer will be 98,496.
