Answer:
Eleana is 20 years old.
Her grandfather is 80 years old.
Step-by-step explanation:
Suppose Eleana's age is "x". That means her grandfathers age is 4x.
x+4x= 100
5x=100 Divide both sides by 5
x=20 That means Eleana is 20 years old.
Her grandfather would be 4 times her age so his age would be 40 years old.
