Question

What is the cost, in dollars, of 16 onions if 3 onions weigh 1.5 lb and the price of onions is 33 cents per kilogram

Answer 1

The cost of 16 onions is $1.1976

Step-by-step explanation:

To find the cost of 16 onions, we need to first find the cost of 1 onion. Given that 3 onions weigh 1.5 lb, we can find the weight of 1 onion by dividing 1.5 lb by 3, which gives us 0.5 lb per onion. Since the price of onions is 33 cents per kilogram, we need to convert the weight of 1 onion from pounds to kilograms. 1 kilogram is equal to 2.20462 pounds, so we have 0.5 lb * (1 kg / 2.20462 lb) = 0.2268 kg per onion. Now, we can find the cost of 1 onion by multiplying the weight (0.2268 kg) by the price (33 cents per kilogram).

Cost of 1 onion = 0.2268 kg * $0.33/kg = $0.0748

Finally, to find the cost of 16 onions, we multiply the cost of 1 onion by 16.

Cost of 16 onions = $0.0748/onion * 16 onions = $1.1976

Answer 2

The cost of 16 onions is $ 1.20.

Step-by-step explanation:

To determine what is the cost, in dollars, of 16 onions if 3 onions weigh 1.5 lb and the price of onions is 33 cents per kilogram, the following calculation must be performed:

1.5 pounds = 0.68 kilos

0.68 / 3 = 0.22666 kilos each onion

16 x 0.22666 = 3.626 kilos

0.33 x 3.626 = 1.20

Therefore, the cost of 16 onions is $ 1.20.
