There were 85 erasers in box a and 15 erasers in box
b. when an equal number of erasers were added to each box, the number of erasers in box a was 3 times as many as that in box
b. how many erasers were added to each box? explain
there were 20 erasers added to each box, because 15 plus 20 is 35. 85 plus 20 is 105, and 35 times 3 is 105. This means that there are 35 erasers in box B after adding 20, and 105 erasers in box A after adding 20. I hope this helps you!
