Answer:
3 Lemonade
Step-by-step explanation:
We add $1.00 with $0.10, then we get $1.10
We then divide $1.10 to the amount Sara paid
$3.60/1.10, we will get the answer 3
Answer:
Answers are: (x+3)(x+5) = 0
So first zero: x+3 = 0 so x = -3
Second zero: x+5 = 0 so x = -5
so zeros are: x = -5 and -3
Step-by-step explanation:
Part A: Chose some value for x, that means any amount of books to print for example 100 books, so x=100
Replace x=100 in C(x) and solve:
C(100)=3.5*100+1200=1550
Part B: Replace C(x) by 1900 and solve for x from the given equation:
1900=3.5x+1200
3.5x=1900-1200
x=700/3.5= 200
Part C: the statement C(20)=1270 means that 1270 is the cost for printing 20 books.
Part E: C(40.5)=1341.75 I think this statement is incorrect given the context because x means number of books to print so this value must be an integer number.
