First, we need to find out how much one gallon cost so we do 16.76/4= 4.19.
one gallon equals $4.19

Then 4.19 times 7= 29.33

7 gallons= $29.33

To solve this, you can make a proportion with gallons of milk as the numerator and the cost as the denominator: 4/16.76=7/x, where x=the cost for 7 gallons of milk. Then, you cross multiply to get 4x=7*16.76 or 4x=117.32. Then, you divide both sides by 4 to get x=$29.33. 

I hope this helps.
