Question

Alicia cashed her paycheck and used half her earnings to take three friends out to dinner. She spent $42.15 and she brought home more than $20. Write an inequality to represent the situation, using X to represent the amount of Alicia's paycheck

Answer 1

If you would like to write an inequality to represent the situation, using X to represent the amount of Alicia's paycheck, you can calculate this using the following steps:

X ... the amount of Alicia's paycheck

X/2 - $42.15 >= $20
X/2 >= $20 + $42.15
X/2 >= $62.15     /*2
X >= $62.15 * 2
X >= $124.3

The correct result would be X >= $124.3.
