an averaga-sided female spider and a large spider can lay a total of 2100 eggs at one time. the large spider lays 20 times the number of eggs as the average sized spider. how many eggs does the average side spider lay?
Ls=large spider as=average sized spider
The average sized spider lays 100 eggs at one time
let the no. of eggs laid by average side spider=x
given, 20x= 2100
divide both sides by 20
20x/20 = 2100/20
. the no. of eggs laid by an average side spider = 105 eggs
