Question

Alicia cashed her paycheck and used half her earnings to take three friends to dinner. She spent $42.15 on dinner and she brought home more than $20.00. 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, you can do 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.
