Riley is selling each of the braided rugs she makes for $54.99 each at the craft fair. It costs $27 for the material to make 3 rugs. How many rugs should she sell to earn a profit of at least $580?
A. Riley should sell 21 rugs.
B. Riley should sell 20 rugs.
C. Riley should sell 13 rugs.
D. Riley should sell 12 rugs.

C. 13 rugs

Step-by-step explanation:

13/3 = 4.3

4.3 x 27 = 116

54.99 x 13 = 714.87

715-116 = 599

- This is as low as you can go without going under the minimum profit of $180. Option D will get a profit of $551, but that is to low and therefore makes C. the valid answer.

- Hope this helps! If you would like a more indepth explanation please let me know, as I would be glad to help.

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
