Hi, I need help with this question:-

Thank you very much.

At first
D 12u + 22

B 12u

Spend
D 1/4 of (12u + 22) --> 3u + 5.5

B 1/6 of 12u --> 2u

3u + 5.5 --> 8 + 2u
1u --> 2.5

a)

2u --> 2*2.5 = 5

Bend spent $5

b)

the total amount of money the two boys had left was
= (12u + 22) + 12u - (3u + 5.5) - 2u
= 19u + 16.5
= 19*2.5 + 16.5
= 47.5 + 16.5
= 64

Thank you very much.

1/6 of Ben's money (spent)--> 1 unit, Ben's money --> 6 units
1/4 of Daniel's money (spend) --> 1 unit + $8, Daniel's money --> 4 units + $32

Ben had $22 less than Daniel,
So, 6 units (Ben's money) + $22 = 4 units + $32
1 unit --> $5

a) Ben spent --> $5
b) Daniel spent --> $5 + $8 = $13
Total amount left --> 5 x $5 + 3 x $13 = $64

cheers.
