N=12
1/4n = 10-7
1/4n = 3
N = 3x4 = 12
It would be 12% of 50
50 * 12/100 = 600/100 = 6
so, 6 cars are red

Assume M is the Total Money
M/6 + (1/5)(M - M/6) + $600 = M
M/6 + M/5 - M/30 + $ 600 = M
M/6 + M/5 - M/30 - M = -$600
(1/6 + 1/5 - 1/30 - 1)M = -$600
-2M/3 = -$600
2M/3 = $600
M = ($600)(3/2)
M = $900
so the total money is $900
but the money he gave to his children is only 1/3 of the Total Money(M)
therefore,
=(1/3)($900)
=$300
$300 is the total money he gave to his children

Answer: A.$23.00
Step-by-step explanation:
This question is incomplete, please remember to be carful and submit the whole question :)
However, if we assume the money Tommy's class substracted from its penny collection is
, we will have the following:
<em>Marty's class collected
in a school-wide penny collection contest. If Tommy's class collected,
, then substracted
and then multiplied the difference by 2,they would have the same amount of money as Marty's class. How much money did Tommy's class collect?</em>
<em />
This can be mathematically expressed as follows:

Isolating
, which is the amount of money Tommy's class collected:



Hence, the correct option is A.
