310 Peter's savings : Total savings = 3 : 10
Elijah's savings = 30 u
30 u = 450
1 u = 450 ÷ 30 = 15
Peter's savings = 21 u
Savings of the other three boys
= 30 u + 5 u + 14 u
= 49 u
Savings that Peter had less than the total of the three other boys
= 49 u - 21 u
= 28 u
= 28 x 15
= $420
Answer(s): $420
