3.01 discussion: problem solve with decimals
congratulations! you just got a job! it pays $15.75 an hour. you will finally have money to save up for that special item you always wanted. how many hours will you have to work to save up for it?

a. pick a job title and an item to purchase, then look up how much it might cost. then determine the hours you will have to work making $15.75 an hour to be able to purchase the item. (don’t worry about taking out taxes or saving for retirement. you’re too young for that now.) post your information to the discussion board.
b. respond to two other students’ posts and give them a raise! be generous. they’re working hard! let each student know what their new hourly wage is (be sure to include a decimal, for example $16.28) and ask them to figure out how many hours it will take before they can purchase their item at the new wage.
c. respond to two replies to your post and figure out how many hours it will take to purchase your item at your new wage.

Aplane flies a distance d from west to east at a constant speed vp , with respect to the air in a time twe . on the return trip, the plane flies a distance d from east to west at a constant speed vp , with respect to the air in a time tew . on both trips the wind blows from west to east at a constant speed va , with respect to the ground 1) what is tew in terms of vp, va, and d, as needed? tew=dvp tew=dvp+va tew=dva tew=dvpâ’va tew=12dvp tew=12dvp+va tew=12dvpâ’va your submissions: b submitted: saturday, january 26 at 6: 49 pm feedback: feedback will be given once all questions have been attempted and the grade cluster button has been pressed. 2) what is twe in terms of vp, va, and d, as needed? twe=dvp twe=dvp+va twe=dva twe=dvpâ’va twe=12dvp twe=12dvp+va twe=12dvpâ’va your submissions: d submitted: saturday, january 26 at 6: 49 pm feedback: feedback will be given once all questions have been attempted and the grade cluster button has been pressed. 3) assuming d = 2300 miles, vp = 400 miles/hr, and twe = 4 hours, what is va, the speed of the wind with respect to the ground? va = 100 miles/hr va = 575 miles/hr va = 200 miles/hr va = 175 miles/hr va = 975 miles/hr 4) once again, assuming d = 2300 miles, vp = 400 miles/hr, and twe = 4 hours, what is tew, the time it takes the plane to fly a distance d miles from east to west? tew = 5.75 hours tew = 11.5 hours tew = 7.67 hours tew = 8 hours tew = 10.2 hours
