Answer:
It would cost 12.60 dollars for the company in the problem. If you could send the other company's deal I could write the answer in the comments.
Step-by-step explanation:
100% - 30% = 70%
70% to demical = 0.7
So, I would do...
18 times 0.7 to get 12.6
The answer you get would be $12.6
The formula I used for this was...
( T ) * ( 1 - S ) = F
T is the Total cost
S is the amount of sale in percent to decimal form
F is the final amount
Hope this helps :)
