A ceramics workshop makes wreaths, trees, and sleighs for sale at Christmas. A wreath takes 3 hours to prepare, 2 hours to paint, and 9 hours to fire. A tree takes 14 hours to prepare, 3 hours to paint, and 4 hours to fire. A sleigh takes 4 hours to prepare, 15 hours to paint, and 7 hours to fire. If the workshop has 116 hours for prep time, 64 hours for painting, and 110 hours for firing, How many of each can be made?
A. 8 wreaths, 6 trees, 2 sleighs B. 6 wreaths, 2 trees, 8 sleighs C. 9 wreaths, 7 trees, 3 sleighs D. 2 wreaths, 8 trees, 6 sleighs
call number of wreaths w , trees t and sleighs s. now you have 3 equations with 3 unknowns: 3w + 14t + 4s = 116 2w +3t + 15s = 64 9w+4t+7s=110
i thought u cant add unlike terms
each equation is for different "process"
ya i have no clu w/ this one
do you know how to solve these equations ?
another way is plugging the answers into the equations .. the answer that satisfies all 3 equations is the correct one
ohh ok gimmie a min to figure it out .. sry this ones easy went right over my head
but solving them is better since you wont always have answers. so lets do it using both elimination and substitution. if you multiply the first equation by 3 then subtract the 3rd one from the first you have: 38t+5s=238
ok. we can keep on solving it if you wish
it would b a correct?
yes, A is the correct answer
but, it is really good practice to solve the equations by hand and not substituting answers
but, it's up to you :)
its hard for me on the computer ... hence y im having some trouble in this class but im almost done thank god
