Answer this question:Hayes does 3 loads of laundry a week using a detergent pod for each load. His detergent pods come 39 to a pack. How many packs of detergent pods will he need to do a full year of laundry?
He uses 3 detergent pods a week and there are 52 weeks in a year, so he uses 3 * 52 = 156. His detergent has 39 pods per pack and he needs 156 pods, so he will need 156 / 39 = 4 packs of detergent pods.

Answer this question:There is three less than four times the number of students in Elementary School as there are in Middle School. If the number of students in Middle school is 50, calculate the total number of students in both levels.
The number of students in elementary school is three less than four times the number in middle school: 4 * 50 students = 200 students. This means that there are 200 students - 3 students = 197 students in Elementary school. The total number of students in both levels is 197 students + 50 students = 247 students.
The answer is 247.
