Answer:
190 cans
Explanation:
Total cans collected by Jacob and Dustin for the school can job = 245
Amount of cans they both gave to Dustin's little sister = 55
Now because they gave out cast out of the total they initially had, there would be a deduction in the amount both boys would now have.
To determine the amount the boys are left with, we would deduct 55 casts from the amount they had which 245.
Amount of cans left = 245-55 = 190
Amount of cans left for the boys class = 190 cans
