The equation relating the number of cars to the number of passengers is p = 4n
<em><u>Solution:</u></em>
Given that certain type of car has room for 4 passengers
To find: write an equation relating the number of cars to the number of passengers
Let "n" be the number of cars
Let "p" be the number of passengers
From given information,
Car has room for 4 passengers. Therefore, we can frame,
number of passengers = 4 ( number of cars )
p = 4 (n)
p = 4n
Thus the equation relating the number of cars to the number of passengers is p = 4n

3 no. Answer is 33 in my gess
Remark
Whatever the original price, he gets 70% in the first instance.
He gets 80% in the second instance.
He gets 90% in the third instance
His total income is 240 dollars.
Let the original price be x
Equation
70%x + 80%x +90%x = 240
70% = 0.7 ; 80% = 0.8 ;90% = 0.9
Solution
0.7x + 0.8x + 0.9x = 240 Take out x as a common factor and add the decimals.
x (0.7 + 0.8 + 0.9) = 240
2.4x = 240 Divide both sides by 2.4
x = 240/2.4
x = 100
So the watches should have brought in 3*100 = 300 dollars.
He only brought in 240 dollars.
He lost 300 - 240 = 60 dollars.
The answer is B.
