B

Step-by-step explanation:

When you are solving these kinds of problems, it's always best to start with getting rid of the decimal/fraction.

We can actually solve for a.

2/3*3=6/3=2

(15+2a=-5)

a=-10

(15+(-20)=-5)

TRUE

a=10 (I think)

D

Step-by-step explanation:

You want to move all terms not containing a to the right side of the equation.

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300
