The two shaded areas are of different sizes.
The lower square is 1/4 of ABCD.
Divide the top square into 4 equal triangles.
The top square is 4/18 or 2/9 of ABCD.
Fraction of ABCD which is shaded ------ 1/4 + 2/9 ------ 17/36

Total money 28 x 3 x $0.50 = $42
J - u
R - u u u u
M - u u u u $7
1u = ($42 - $5)/9 = 35/9
M-J = 3u +$7 = (3 x 35/9) + $7 = $18 2/3[/quote]
As no guided answer was provided, my son got his answer: $17.50 .

Every time Nora saved 70 cents, her father put another 20 cents into her savings. When Nora had $23.40 in her savings, how much of it had been put in by her father? -
nora father total
0.7 0.2 0.9
total $23.4
$23.4/$0.9 = 26 sets of $0.7 and $0.2.
26 x $0.2 = $5.2
Am I right ?
