## mamma17 2 years ago 3. A drama club is planning a bus trip to New York City to see a Broadway play. The cost per person for the bus rental varies inversely as the number of people going on the trip. It will cost $30 per person if 44 people go on the trip. How much will it cost per person if 60 people go on the trip? Round your answer to the nearest cent, if necessary.$22.00 $40.91$1,320.00 $21.29 • This Question is Closed 1. KingGeorge Again, you start with the equation$y=\frac{k}{x}$since it's inversely proportional. What should we now put in for x and y? 2. mamma17 y=30? and x=60? 3. KingGeorge We're assuming x is the number of people, and y is the cost per person. We know that when 44 people go, it costs 30 dollars per person. So we use y=30 and x=44. 4. mamma17 oh ok 5. mamma17 so it would be 1,320.00 6. KingGeorge That's your $$k$$, but not the price per person. Now you need to go back to $y=\frac{k}{x}$ except now you know k, and you're told to find y when x=60. 7. mamma17 u are smart with math lol u wanna do all my math work lol jk jk jk 8. omgitsjc 1. Suppose that y varies jointly with w and x and inversely with z and y = 540 when w = 15, x = 30, and z = 5. Write the equation that models the relationship.
