125.
16 (10 and 6) divided by 100 is 6.25. Times two is 12.5. (For 200) times 10 for 10 marbles.
Answer:
158 quarters
54 dimes
Step-by-step explanation:
Let d = no. of dimes
q = no. of quarters
10d = value of all the dimes since each dime is worth 10 cents
and 25q = value of all the quarters since each quarter is worth 25 cents
$44.90 = 4490 cents
10d + 25q = 4490 d + q = 212
<u> - 10d - 10q = -2120</u>
15q = 2370
q = 158 quarters d + 158 = 212
d = 54 dimes
If there is 23 classrooms and each has 10 then you would have to times 23 by 10 - 23x10=230
