Answer: The correct statements are 'The equation 2n = p should be 2p = n' , 'The actual cost of the onions is $3.00 per pound' and 'Potatoes cost $1.50 per pound.'
Step-by-step explanation:
Here, p represents cost of one potato and n represents the cost of one onion.
And, According to the question, He purchases 6 pounds of potatoes, p, and 3 pounds of onions, n, for $18.
Therefore, 6p +3n = 18 ------(1)
And, Onions cost twice as much as potatoes.
Therefore, n= 2p ---------(2)
Putting the values of n from 2) in equation 1),
we get, 6p+3(2p)=18
⇒6p+6p=18 ⇒ 12p =18 ⇒ p = 1.5 dollar.
Thus cost of one potato= $1.5
And cost of one onion = $ 2× 1.5= $ 3.00
Thus with help of above explanation we can say that Options first, third and fifth are correct.
