Acompany makes tables and chairs. each table is assembled from 6 pieces of wood and 5 pieces of plastic, and each chair is assembled from 9 pieces of wood and 12 pieces of plastic. each piece of wood (in either a table or a chair) is attached with 3 screws and 2 bolts, and each piece of plastic (in either a table or a chair) is attached with 4 screws and 5 bolts. screws cost 4¢ each and bolts cost 8¢ each. use matrix multiplication to answer the following questions.
a) what is the cost of assembling a table? (give your answer in ¢: for example 983 rather than $9.83)
b) what is the cost of assembling a chair? (give your answer in ¢: for example 983 rather than $9.83)

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
