35100 =
720The number of 50-cent coins and $1 coins is the same.
Number of 5-cent coins
= 20 u - 7 u - 7 u
= 6 u
$1 = 100¢
$48 x 100 = 48 x 100 = 4800¢
Number of more 50-cent coins than 5-cent coins
= 350 u - 30 u
= 320 u
320 u = 4800
1 u = 4800 ÷ 320 = 15
Total number of coins that Reggie had
= 6 u + 7 u + 7 u
= 20 u
= 20 x 15
= 300
Answer(s): 300
