Answer 1

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 $\ 15$, we will have the following:

Marty's class collected $16.00$ in a school-wide penny collection contest. If Tommy's class collected,$x$, then substracted  $\ 15$ 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?

This can be mathematically expressed as follows:

$(x-\ 15)2=\ 16$

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

$2x-\ 30=\ 16$

$x=\frac{\ 46}{2}$

$x=\ 23$

Hence, the correct option is A.
