Mr. yi buys vegetables at a market. he purchases 6 pounds of potatoes, p, and 3 pounds of onions, n, for $18. onions cost twice as much as potatoes. to determine the unit price for each item, his daughter sets up and solves the system of equations shown. 6p + 3n = 18 and 2n = p 6(2n) + 3n = 18 12n + 3n = 18 15n = 18; n = $1.20 onions cost $1.20 per pound. analyze the daughter’s solution. which statements are true? check all that apply.
the equation 2n = p should be 2p = n. the equation 6p + 3n = 18 should be
6n + 3p = 18.the actual cost of the onions is $3.00 per pound. potatoes cost $0.60 per pound. potatoes cost $1.50 per pound. potatoes cost $2.40 per pound.
