In a contest to guess the number of jelly beans in a jar, alice guessed 25; betty, 18; clare,23; dotty,19; edith,24; and fran,17. two were off by 2, two were off by 3, two were off by 4. how many beans are in the jar?

There are 21 jelly beans in the jar.

Step-by-step explanation:

Suppose, the number of jelly beans in the jar is  

Two were off by 2, two were off by 3, two were off by 4. That means, the six guessed number will be:  

Given that, Alice guessed 25; Betty, 18; Clare, 23; Dotty, 19; Edith, 24; and Fran, 17.

So, the sum of all six guessed number will be:  

Thus, the equation will be..........

So, the number of jelly beans in the jar is 21.

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two
