( 2x − 27 ) ( −x + 15 )
= ( 2x + −27 ) ( −x + 15 )
= ( 2x ) ( −x ) + ( 2x ) ( 15 ) + ( −27 ) ( −x ) + ( −27 ) ( 15 )
= −2x^2 + 30x + 27x − 405
= −2x^2 + 57x − 405
Answer:
The price before tip ,Mrs. Henry's move is 351.9 $
Step-by-step explanation:
Given:
Total bills of 414 $ in which 15 % is tip
To Find:
What is the price before tip, Mrs. Henry's move
Solution:
Total bill amount is 414$
And 15 % is tip bill and 85 % is bill before tip
So,
85 % of total bill can give price before tip
OR
calculate 15 % and subtract from total bill.
So 85 % of 414=0.85 *414
=351.9 $
OR
15 % 414=0.15 *414
=62.1 $
Price before Tip is =414$ -62.1 $
=351.9$
So BY Both ways we can get same answer i.e. 351.9 $
