Question

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

Answer 1

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!
