Alice works part-time after school. On Monday, Alice records that she worked three and one-fourth hours. On Tuesday, Alice records that she worked one and three-fourth
hours. On Wednesday, Alice records that she worked two and two-thirds hours. On
Friday, Alice records that she worked five and one-half hours. Alice knows that she
worked sixteen and one-half hours for five days. Alice forgot to record how many hours
she worked on Thursday. How many hours did Alice work on Thursday? Alice earns
seven dollars and fifty cents per hour. Alice needs one hundred forty-six dollars and
twenty-five cents to buy a new game player. How many more hours does Alice have to
