Please i need help this is do mon. for math and if i won't get it right i'll get a 0% i am already 68%

A flower shop charges a $10 delivery fee and $1.50 per rose.





a. Write an expression that can be used to calculate the total cost for purchases


'r' roses:__________________





b. Use your expression to find the total cost of 2 dozen roses:





please help!!!!!!!

A. 10$ + R x 1,50





10$ , because you'll have to pay that without buying any roses.


and 1,50 x R because the number of times you buy a rose (R)


Determines how much you'll have to pay








B. 10 + (24 x1,50) = 46


36+10=46$


You'll have to pay 46 dollars for 2 dozen roses
Reply:10 + 1.50r, let r = # of roses





2 dozen roses = 24 roses





so plug in 24 for r in the equation


10 + 1.50(24)


10 + 36


46





so it costs $46 for 2 dozen roses
Reply:a. 10+1.5r





b. substituting: 10+1.5(24)=10+36=$46


$46
Reply:The total cost is: $10 plus $1.50 for each rose purchased





So, if r roses are purchased, the total cost, C, is





C = $10 + $1.50 x r.





If 2 dozen ( that`s 24) roses are purchased, then:





C = $10 + $1.50 x 24, so





C = $10 + $36, so





C = $46.





Hope this helps, Twiggy.
Reply:a. $1.50r +$10





b. $1.50(24) + $10 = $46
Reply:Perhaps you should start working a little harder in Math. How are you going to pass the test if yahoo answers gives you the assignment questions?





Sigh anyway,





a. cost=1.5*r+10


b. 1.5*24+10=$46
Reply:a: 'r' roses: $10 + $1.50r





$10(delivery fee) plus r times $1.50





b. 2 dozen = 24 roses = 'r'





$10 + $1.50 x 24 = $10 + $36 = $46





do u understand(: if not,ask again,i'll explain
Reply:P(for r roses)= 10+(1.50)r


P(12 roses)=10+(1.50)*24


=10+36=$46 ans
Reply:a) since there is always a $10 charge that number does not change. each rose costs $1.50 so that is where your variable will go:


cost=10+1.50r





b) plug in 24 where there is an 'r':


cost=10+1.50(24)


cost= 10+36


cost=$46
Reply:The answer is quite simple. Since the delivery charge is always $10 you have to add that to the total amount for the r flowers so:


n = 1.5r+10


where n is the total amount of money owed.


dozen= 12


so answer b. is n= 1.5(r)+10


=1.5(24)+10


= $46
