Jenson had
16 as many marbles as Brandon. Brandon had twice as many marbles as Neave. If Jenson had 42 marbles fewer than Neave,
- how many marbles did Jenson have?
- how many marbles did they have altogether?
(a)
Number of marbles that Jenson had = 1 u
Number of marbles that Brandon had = 6 u
Number of marbles that Neave had = 6 u ÷ 2 = 3 u
Number of marbles that Jenson had fewer than Neave
= 3 u - 1 u
= 2 u
2 u = 42
1 u = 42 ÷ 2 = 21
Number of marbles that Jenson had
= 1 u
= 21
(b)
Total number of marbles that they had
= 1 u + 6 u + 3 u
= 10 u
= 10 x 21
= 210
Answer(s): (a) 21; (b) 210
