Jan bought a blazer for $39.90. The price of the blazer was $38. What sales-tax rate was she charged for this blazer?

Answers

Answer 1

Answer: The sales tax rate was 5% because $38 x .05 = $39.90

Answer 2

Answer: First find the amount of sales tax by Subtracting 39.90 - 38 = 1.90
The amount of sales tax is $1.90. Since sales tax is found by multiplying the tax rate (in decimal form) times the original cost, we have this equation:
Sales tax = rate * original cost.
We know that sales tax is $1.90 and the original cost is $38.
Plug these numbers into the equation:
1.90 = r * 38
Solve for r by dividing both sides by 38:
r = 0.05
This is in decimal form, so convert it to percent form by moving the decimal 2 places to the right.
Sales Tax rate = 5%

If 48 is added to one-third of a number, the triple of the number is the result. What is the number?

Answers

Until we know what it is, let's call the number ' M ', for 'Mystery number'.

      The number . . . . M
   The triple of the number . . . 3M
   One third of the number . . . . M/3
48 added to one third of the number. . . . M/3 + 48 .

You said that 48 added to one third of the number makes triple the number,
so I can write
    M/3 + 48 = 3M
and the rest is easy.

Multiply each side by 3 : M + 144 = 9M

Subtract M from each side: 144 = 8M

Divide each side by 8 : 18 = M

Check:

   Is M/3 + 48 equal to 3M ?

   (18/3) + 48 ? = ? 3(18)

   6    + 48 ? = ? 54

54 = 54

Write the ratio in lowest terms. 20:14a. (7/10)
b. (20/14)
c. (14/20)
d. (10/7)

Answers

when putting ratios, fractions, expressions, etc into lowest terms you take out the gcf.

in this case the gcf of both 20 and 14 is 2.

20/2:14/2 = 10:7

the answer is d

to get a ratio in lowest terms, you have to divide both sides by the same number. what number fits into both? 2 does. so 20/2=10, and 14/2=7. this means that (d) is correct.
does that help?
