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:
45
Step-by-step explanation:
The 4 part of the ratio represents Pip's 20 sweets
Dividing 20 by 4 gives the value of one part of the ratio
20 ÷ 4 = 5 sweets ← value of 1 part of the ratio
Thus
Pip gets 20 sweets
Angad gets 20 sweets ( 4 parts of the ratio )
Nick gets 5 sweets ( 1 part of the ratio )
Total number of sweets = 20 + 20 + 5 = 45
Part A.
Consider a punch containing L liters.
60% of these that is

is grape juice, and the rest, 0.4 L is lemon-soda.
so, for the variable L, the total amount of punch, the total amount of grape juice is 0.6 L
and the amount of lemon soda in the punch is 0.4L
Part B.
For L=2, we substitute and get:
0.6 L=0.6 * 2 liters = 1.2 liters of grape juice
0.4 L = 0.4 * 2 liters = 0.8 liters of lemon soda.
