the cost of 6oz. of chicken is $2.00. how much would it cost for 1.5lbs. of chicken ? (16oz=1lb.)
2 simple ways:
1.
if 6 oz cost 2.00
then 1 oz costs 2.00/6 = .3333.
and then 16 oz cost 16(.3333..)
=5.33
2. by ratios
2.00/6 = x/16
cross multiply and solve for x
you will get the same calculations as above.
To calculate the cost of 1.5lbs of chicken, we can use two simple methods:
1. Proportional Method:
First, we determine the cost of 1 ounce of chicken by dividing the cost of 6 ounces ($2.00) by 6: 2.00 / 6 = 0.3333 (rounded to 4 decimal places).
Next, we multiply the cost per ounce by the total number of ounces in 1.5lbs (1.5lbs * 16oz/lb = 24 ounces): 0.3333 * 24 = 7.9992 (rounded to 4 decimal places).
Therefore, it would cost approximately $7.99 for 1.5lbs of chicken.
2. Ratio Method:
We can set up a ratio by comparing the cost of 6 ounces to the cost of 16 ounces (1 pound):
2.00 / 6 = x / 16
Next, cross multiply to solve for x:
6x = 2.00 * 16
x = (2.00 * 16) / 6
x ≈ 5.33
Therefore, it would also cost approximately $5.33 for 1.5lbs of chicken using this method of calculating ratios.
Both methods will yield the same result, giving us an estimated cost of $7.99 or $5.33 for 1.5lbs of chicken.
