Question

Jeremy, Sue, and Holly are siblings. Sue was born three years before Holly, and Jeremy was born five years before Sue. The product of Sue's age and Jeremy's age is at most 150. If x represents the age of Holly, which inequality can be used to find the age of each sibling?

Answer 1

If Holly's age is x then
sue's age=x+3
Jeremy's age=8+x

Answer 2

(x-3) (x-8)≤150

Explanation:

Let the age of Holly be represented as 'x',then

the age of Sue will be: x-3 and the age of jeremy will be x-8,

The product of Sue's age and jeremy's age is atmost 150 then,

(x-3) (x-8)≤150

This inequality can be used to find the age of each sibling.
