Answer:
The ratios 2.56/32 and 0.48/6 are equivalent; y = 0.08x.
Step-by-step explanation:
$2.56 for 32 oz is a unit price of $2.56/(32 oz) = $0.08/oz
$0.48 for 6 oz is a unit price of $0.48/(6 oz) = $0.08/oz
The unit prices are equal, so the cost of both sizes are proportional.
If x is the weight in oz, multiply the weight by 0.08 to get the cost, y, in dollars.
y = 0.08x
The ratios 2.56/32 and 0.48/6 are equivalent; y = 0.08x.
