Given:
8 oz bottle of ketchup = $1.39
Determine how much should a 14oz bottle cost, if the unit rate stays the same.
Solution:
In order to determine how much should a 14oz bottle cost, we must know first the cost per oz. This can be done by dividing 1.39 with 8.
= $1.39/8oz
= $0.17375 per oz
Now that we know the cost per oz, we simply multiply it with 14oz .
=( $0.17375 per oz)(14 oz)
=$ 2.4325
Therefore a 14oz bottle of ketchup will cost $2.43.
