This problem ( opportunity) is really about attention to detail.

Mathematically, we need to use the distributive property.

2 (3g -4) = 6g -8

-(8g + 3) = -8g -3

Put em together:  6g – 8g definitely-2g. Look at all the answers:  they all have-2g

Put em together: -8 – 3. Here’s the decision point

-8 less 3 or you lose $8, you lose $3,  or you can use a number line!

That’s awesome…2 more points!!
