Q13.
In the end
J:E = 3:1
J:E = 15:5
At 1st:
J= 15u+186
E= 6u
At 1st = $564
15u+186+6u = 564
21u = 378
1u = 18
J at 1st = (15x18) + 186 =456
E at 1st = 6u = 6 x 18 = 108
Ratio
J:E
=456:108
=38:9
Hope this helps

Q14.
In the end
$10 : $5
=2 : 1
=6 : 3
(40% of $10 notes) : (75% of $2 notes)
75% = 3/4, so made the $2 note to 3u)
At 1st
$10 : $5
= 15 : 4
(60% of $10 notes): (25% of $2 notes)
Therefore, 15u+4u = 57
19u = 57
1u = 57/19
1u = 3
$10 notes at 1st = 15u
= 15 x 3
= 45
60% of 15 = 15 x 0.6 = 9
Value = 9 x $10 = $90
$5 notes = 4u
= 4 x 3
=12
25% of 12 = .12 x 0.25 = 3
Value = 3 x $5 = $15
Bags cost = $90 + $15 = $105
Hope this helps
