The equation would be 35x +10 = 150
35x =140 (subtraction property)
x = 4

Whenever you have a decision tree like this, the probability of reaching a specific leaf is the multiplication of the probabilities of each step you have to reach the leaf.
So, in order to reach the "hardcover and nonfiction" leaf, we have to take the "buys hardcover" branch (probability 0.35), and then the "buys nonfiction" branch (probability 0.55).
Given what we said above, the probability for "hardcover and nonfiction" is

40 km/3 L = x km/ 50 L
40 km * 50 L = x km *3 L
2000 = 3 * x
X = 666 km
Answer:
Interest Manny earns after 2 years is $52
Step-by-step explanation:
Amount deposited = $650
Simple annual interest rate = 4%
To find: Interest after 2 years
We know that the formula to calculate the interest amount is
Simple interest (S.I.) = 
where,
P is the initial amount deposited
r is the rate of simple interest in percentage
t is the time in years for which interest is to be calculated
Substituting the known values in the formula, we get
S.I = 
= 52
Hence the interest Manny earns after 2 years is $52
