1 x $1 coin, 8 x 50¢ coin

$1 x 1 = $1
8 x 50¢ = 400¢ = $4

Total = $1 + $4 = $5 (wrong)

2 x $1 coin,16 x 50¢ coin

$1 x 2 = $2
16 x 50¢ = 800¢ = $8

Total = $2 + $8 = $10 (wrong)

5 x $1 coin, 40 x 50¢ coin

$1 x 5 = $5
40 x 50¢ = 2000¢ = $20

Total = $5 + $20 = $25 (wrong)

6 x $1 coin,48 x 50¢ coin

$1 x 6 = $6
48 x 50¢ = 2400¢ = $24

Total = $6 + $24 = $30 (correct)
