5) Mary Anne is planning to landscape her yard. She goes to the flow power store and finds that the average price per flat of perennials is $32.50. She also needs to buy some fertilizer that costs $15.00 per bag. The equation C = $32.60(f) + 15b, where C is the total cost, f is the number of flats purchased, and b is the number of fertilizer bags, can be used to determine her total cost. What is Mary Anne's total cost if she buys 4 flats and 2 bags of fertilizer?
B. $160.00
*I have no answers even though I could get this one by using a calculator*

Well if I knew about that site I would of went to it instead of posting a thread and asking for help, thank you very much.

[trix]

Emily did you get the right answer to 27? (:

Thanks for giving my brain something slightly more sophisticated than neo to do <3 and ty for the rep

It has no answer right now, I don't think anyone answered it yet. No problem :)

[Zachafer]

27) Solve for x. x 5 = 22
A. x = -27
B. x = -17
C. x = 17
D. x = 27

It is either supposed to be x - 5 or x + 5

[trix]

Also for no.16 I am sure it's 180 ! :D

[Emiley]

Okay, thanks everyone! I'll close the thread now that I got enough help.
