Hi There!

Baseball Bats:
43 x 0.45 = $19.35 as the amount off.
43 - 19.35 = $23.65 with the discount.
23.65 x 2 = $47.3 for two bats.
-----------------------------------------------------
Glove:
28 x 0.25 = $7 as the amount off.
28 - 7 = $21 with the discount.
-----------------------------------------------------
Together:
21 + 47.3 = $68.3 as the total before taxes.
-----------------------------------------------------
With Taxes:
68.3 x 0.055 = $3.7565 as the tax amount.
68.3 - 3.7565 = $64.5435

If A, B and C lie on one line then 
Hence, they lie on one line.
You don't need to use a graph paper to prove it.
Answer:
its 60 all around
Step-by-step explanation:
Answer:
x = 0
, y = 7/6
Step-by-step explanation:
Solve the following system:
{18 y - 12 x = 21
6 x - 9 = -9
In the second equation, look to solve for x:
{18 y - 12 x = 21
6 x - 9 = -9
Add 9 to both sides:
{18 y - 12 x = 21
6 x = 0
Divide both sides by 6:
{18 y - 12 x = 21
x = 0
Substitute x = 0 into the first equation:
{18 y = 21
x = 0
In the first equation, look to solve for y:
{18 y = 21
x = 0
Divide both sides by 18:
{y = 7/6
x = 0
Collect results in alphabetical order:
Answer: {x = 0
, y = 7/6
