Calculate the volume of a semi-truck trailer that is 23 feet long, 15 feet wide, and 11 feet high.
The formula for the volume of an object with parallel sides and right-angle comers is Length × Width × Height 23 feet of length × 15 feet of width × 11 feet of height = 3,795 cu ft (cubic feet)
A college student spent $119 on tickets for family and friends to a sporting event.If tickets were $7 and $10, and she bought an equal number of both kinds of tickets, how many $7 tickets did she buy?
Answer(s): C
Let v be the number of tickets bought at each price (remember, the student bought the same number of both kinds of rickets).So, 7v + 10v= 119Now combine the terms and continue solving the equation for v.17v =119v = 7
Amanda earns an average of $22 an hour in tips as a waitress at the best steak restaurant in town.If her hourly wage is $2.50 and she has to pay a 10% tip share to the hostesses and busboys, how much does she take home at the end of a day when she worked from 10:00 a.m. to 5:00 p.m.?

During Friday night's high school performance of the play Seven Brides for Seven Brothers, 76% of the seats in the performing arts center (with a seating capacity of 500 people) were occupied, and three-quarters of those attending were parents.How many high school students attended the play?
Answer(s): A
The first step is to calculate the number of total playgoers by multiplying the total seats available by the percentage.500 × 0.76 = 380Since three quarters (75%) of those attending were parents, that means that one quarter, or 25%, were high school students; this is the answer we are going to calculate. Therefore, multiply the number of total playgoers by the percentage of students to find out how many students attended the performance.380 × 0.25 = 95 students
