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.
