i think the answer is a: $1.20

my work:

3 x 0.15 = 0.45.

6.45 - 0.45 = 6.00

6.00 / 5 = 1.20

and i checked my work by doing 1.20 x 5 + 0.40 = $6.45.

Answer:

Step-by-step explanation:

We move all terms to the left: 15/9-(25/9x)=0 Domain of the equation: 9x)!=0 x!=0/1 x!=0 x∈R

We add all the numbers together, and all the variables

-(+25/9x)+15/9=0

We get rid of parentheses

-25/9x+15/9=0

We calculate fractions

=0 x=0/1 x=0
