Question

Marty's class collected $7.60 in a school-wide penny collection contest. If Tommy's class subtracted $2.30 from the amount they collected, x, and then multiplied the difference by 2, they would have the same amount of money as Marty's class.

Answer 1

Answer: A .$6.10

Explanation:

Hi, to answer this question we have to solve the equation given for x .

2 (x-2.30) = 7.60

Dividing both sides by 2.

[2 (x-2.30)]/2 = 7.60 /2

x-2.30 =3.8

Adding 2.30 to both sides

x-2.30+2.30 =3.8+2.30

x =$6.10

The correct answer is A. Tommy's class collected $6.10
