Let
x-------> the number of hours Ashley worked during the week
y------> Ashley's weekly pay
we know that
Ashley earns $8.50 per hour at her job and if she works more than 35 hours in a week she is paid 1½ times her regular wage for the overtime hours worked
so
case a) if she worked no more than 35 hours

In this case the equation is equal to

case b) if she worked more than 35 hours

in this case


the equation is equal to

therefore
the answer part a) is
