Answer:
18 hours during the week days
Explanation:
weekend pay + week day pay = total pay
93 + week day pay = 232.50
Subtract 93 from each side
93-93 + week day pay = 232.50-93
week day pay = 139.50
She makes 7.75 per hour
139.50 = hours * pay rate
139.50 = hours*7.75
Divide each side by 7.75
139.50/7.75 = hours
18 = hours
