Answer:
$17.50
Explanation:
You have a table with a proportional relationship between weight and price, and the pair (weight, price) = (2 lb, $7.00) given. You want to know the price for a weight of 5 lb.
Proportion
A proportion that can be used to find the missing price is ...
price/weight = x/(5 lb) = ($7.00)/(2 lb)
Multiplying by 5 lb gives ...
x = $7.00 × (5 lb)/(2 lb) = $17.50
The price for 5 lb is $17.50.
