A recipe calls for 8 ounces of black beans or red beans. The cheapest option to buy and use would be _________.
One 8-ounce can of red beans at $1.49.
Two 4-ounce cans of black beans at $0.79 each.
Two 3-ounce cans of black beans at $0.59 each.
Three 3-ounce cans of red beans at $0.65 each.
Detailed Explanation
Choice (one 8-ounce can of red beans at 1.49) is the cheapest option. Calculate each answer option and compare:
Choice (two 4-ounce cans of black beans at 0.79 each): 2 x 0.79 = 1.58.
Choice (one 8-ounce can of red beans at 1.49): 1.49.
Choice (two 3-ounce cans of black beans at 0.59 each): Two 3-ounce cans don’t equal 8 ounces, so this answer can’t be correct.
Choice (three 3-ounce cans of red beans at 0.65 each): 3 x 0.65 = 1.95.
