Q. Mrs.Ramirez's class was getting ready to plant tomatoes. They we're wondering if each package of tomato seeds contained the same number of seeds. They counted the seeds in four packages and found that there was a average of 73 seeds in the package. The first three packages contained 78,71, and 74 seeds, respectively. How many seeds were in the fourth package ?

Yep!

Thank you

You are welcome.

To find out how many seeds were in the fourth package, we can calculate the average number of seeds based on the given information.

Given:
- The average number of seeds in the four packages is 73 seeds.
- The first three packages contained 78, 71, and 74 seeds, respectively.

To find the total number of seeds in the four packages, we can multiply the average number of seeds (73) by the number of packages (4):
Total number of seeds = Average number of seeds × Number of packages

Total number of seeds = 73 × 4
Total number of seeds = 292

Now we subtract the sum of the seeds in the first three packages from the total number of seeds to find the number of seeds in the fourth package:
Number of seeds in the fourth package = Total number of seeds - Sum of seeds in the first three packages

Number of seeds in the fourth package = 292 - (78 + 71 + 74)
Number of seeds in the fourth package = 292 - 223
Number of seeds in the fourth package = 69

Therefore, there were 69 seeds in the fourth package.

4 * 73 = 292

78 + 71 + 74 = 223

292 - 223 = ?
