You can't solve it without another piece of information, so the most you can do is write an equation (3b+ 4p), and once you know how many boxes he bought and the total (to figutre out how many pounds) or how many pounds and the total (to figure out how many boxes) or just the number of boxes and the number of pounds you can figure the problem out.
Answer:
It compares 3 meals to 1 day.
Step-by-step explanation:
"Unit rate" refers to a rate that has 1 unit in the denominator.
(3 meals)/(1 day) . . . . "three meals per day"
has one unit (1 day) in the denominator, so that is a unit rate.
Original volume = 2.5 million liters.
After evaporation, the remaining volume is 2 million liters, therefore
Evaporated volume = 2.5 - 2 = 0.5 million liters.
Percent of water evaporated = 100*(0.5/2.5) = 20%
Answer: 20%
Answer: 1,012 miles
You setup the proportion as 
and solve for x by multiplying 22 miles by 46 gallons resulting in 1,012 miles.
