Answer: A .$6.10

Step-by-step 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
