Question

Julios father is 4 times as old as Julio. The sun of their ages is no less tan 55. What is the youngest age Julio can be? Write an inequality to represent this situation. Solve it and show all work

Answer 1

11

Explanation:

let's make a key:

Julio's age = x

Julio's father's age = 4x

the sum of their ages is no less than 55, so it's equal or more than 55. we have this inequality:

4x+x > 55

5x>55

x>11

so the youngest Julio can be is 11 years old
