The amount that Emily and Paul each had in the end is the same. Make the amount that each had in the end the same. LCM of 3 and 1 is 3.
Total amount that Emily and Paul had at first
= 4 u + 6 u
= 10 u
10 u = 70
1 u = 70 ÷ 10 = 7
Total amount that Emily and Paul spent
= 1 u + 3 u
= 4 u
= 4 x 7
= $28
Answer(s): $28
