The eighth grade field trip to the
museum costs $150 plus $5 for each
student going. The equation for the total
cost of the trip is c = $150 + $5s,
where c represents the total cost and
s represents the number of students. It
will cost $780 for the 8th grade to attend.
How many students attended the trip?

Titus works at a hotel. part of his job is to keep the complimentary pitcher of water at least half full and always with ice. when he starts his shift, the water level shows 4 gallons, or 128 cups of water. as the shift progresses, he records the level of the water every 10 minutes. after 2 hours, he uses a regression calculator to compute an equation for the decrease in water. his equation is w –0.414t + 129.549, where t is the number of minutes and w is the level of water. according to the equation, after about how many minutes would the water level be less than or equal to 64 cups?
