To find the cost of each book, you need to divide the money spent on all of the books by the number of books.
$39 / 10 = $3.90 per book
Answer:
no solution
Step-by-step explanation:
4(9x + 4) = 36x - 7 ← distribute parenthesis on left by 4
36x + 16 = 36x - 7 ( subtract 16 from both sides )
36x = 36x - 23 ( subtract 36x from both sides )
0 = - 23 ← False statement
This indicates the equation has no solution
Your function is:
Y= 29 + 0.35x
X represents the money that Tracy is charged per minute
