<h3>
Answer: 80.58 dollars</h3>
==================================================
Work Shown:
x = amount of money collected before tax is added
3% = 3/100 = 0.03
3% of x = 0.03x = amount of tax
x + 0.03x = adding on tax to original amount
1.03x = amount after tax is added
1.03x = 2766.58
x = 2766.58/1.03
x = 2686 is the amount of money before the 3% sales tax is added
0.03x = 0.03*2686 = 80.58 is the amount of sales tax collected
As a check,
2686+80.58 = 2766.58
which confirms our answer
The cost of the new lacrosse stick is $13.20
B) n=m-a
Add n to both sides, leaving a+n on the left=m on the right
Subtract a from both sides to get n=m-a
Answer:
x = 9
Step-by-step explanation:
Step 1: Write equation
-4 - x = -13
Step 2: Solve for <em>x</em>
<u>Add 4 to both sides:</u> -x = -9
<u>Divide both sides by -1:</u> x = 9
Step 3: Check
<em>Plug in x to verify if it's a solution.</em>
-4 - 9 = -13
-13 = -13
