Let's organize what we know:
T = total amount of flour = 2 tons
1 crate = 8 bags
1 bag = 10 pounds
1 ton = 2000 pounds
Knowing this, let's do some conversions first, so we can keep our units consistent in our calculations:
T = 2 tons = 2 tons * 2000 lbs/ton = 4000 lbs
1 crate = 8 bags = 8 bags * 10 lbs/bag = 80 lbs
Now, let's define our variables and write out an equation:
c = number of crates required
80c = T --> each crate holds 80 pounds of flour
Solve the equation:
80c = T
80c = 4000
c = 4000 / 80 = 50
The supplier needs 50 crates to fulfill the order.
