The function M(s) = 225 + 0.65s represents the material cost of manufacturing gardening scissors when s scissors are produced. T
Llana [10]

Answer:

\frac{279 + 1.8s}{s}                                                        

Step-by-step explanation:

The  material cost of manufacturing gardening scissors when s scissors are produced : M(s) = 225 + 0.65s

The labor cost for producing s scissors: L(s) = 54 + 1.15s

So, total cost of producing s scissors =  M(s)+L(s)

                                                              =  225 + 0.65s+54 + 1.15s

                                                              =  279 + 1.8s          

So, total cost for s scissors =  279 + 1.8s    

So, manufacturing cost for 1 scissor=  \frac{279 + 1.8s}{s}                                                        

Hence the manufacturing cost per scissors is  \frac{279 + 1.8s}{s}

jeffrey purchased and downloaded 12 songs on monday. He purchased 3 songs on tuesday. The cost to download each song is $2. Writ
STatiana [176]

Answer:  2 × 12 + 2 × 3 or 2 × (12 + 3)

Step-by-step explanation:

Here, the cost of one song = $ 2

If the downloaded song on Monday was 12,

Then, the total money spend on Monday = 2 × 12

Similarly, If the downloaded song on Tuesday is 3,

Then, the total money spend on Tuesday= 2 × 3

Thus, the total cost of the songs on Monday and Tuesday = 2 × 12 + 2 × 3  Or  2 × ( 12 + 3)

Which is the required numerical expression.

By solving it we get = 2 × 15 = 30

Therefore, he spent $ 30 on Monday and Tuesday in downloading songs.

They didn’t use a ruler I think they made their own materials from what they had. Also thank you.
