1 50⊄ coin → $0.40 more than 1 10⊄ coin
$9.20 → 9.20÷0.40 = 23 coins
Therefore, total have
23 50⊄ coins and
23 10⊄ coins
Total value
= 23 × $0.5 + 23× $0.10
= $11.50 + $2.30
= $13.80
$9.20 → 9.20÷0.40 = 23 coins
Therefore, total have
23 50⊄ coins and
23 10⊄ coins
Total value
= 23 × $0.5 + 23× $0.10
= $11.50 + $2.30
