Question

Juanita is 13 years older than her cousin. The sum of their ages is no less than 103 years. Enter an inequality that can be used to represent this situation in the first box, where x represents Juanita's cousin's age.

Answer 1

Please see below solution:

y = x + 13
y + x ≥ 103
x + 13 + x ≥ 103
Inequality is:
2 x + 13 ≥ 103
2 x ≥ 103 - 13
2 x ≥ 90
x ≥ 90 : 2
x ≥ 45
The youngest age Juanita`s cousin can be is 45.
