Question

Two siblings get bags of Jelly Beans and start eating them at different speeds. After a while Maya has 3 times as many Jelly Beans as her brother Tommy. If Maya is given 20 more beans by a friend, she will have 7 times as many beans as Tommy. How many Jelly Beans does Tommy have?

Answer 1

3t + 20 = 7t
20 = 7t - 3t
20 = 4t
20/4 = t
5 = t.....Tommy has 5 jelly beans
