I purchased a notebook for $3.50 and a pack of pencils for $ 2.50. If the sales tax was 7%, what is the total cost of my purchases? *

Answers

Answer:

6.42 dollar

Step-by-step explanation:

(3.5+2.5)x0.07+(3.5+2.5)

=(3.5+2.5)x(1+0.07)

=6x1.07

6.42

3.50 + 2.50 x 7% = 6.42or
3.50 + 2.50 x 0.07 = 6.42

The quotient of a number and -9 increased by 10 is 11.Translate the sentence into an equation. then find the number that is described in the sentence.
I would like you to use the two-step equation process please.

Answers

so the division of a number and -9 or
x/-9

+10=11 or

(x/-9)+10=11
subtract 10 from both sides
x/-9=1
multiply both sides by -9
x=-9
Your equation would look like this . . .

n/-9 + 10 = 11

*solve by subtracting 10 from both sides, and then multiplying both sides by -9

n = (11 + 10)*-9 = -9

n = -9

Answer:

760 feet

Step-by-step explanation:

Area of the parallelogram = base times height

So 40 times 38 = 1520 feet

Area of rectangular walkway = 38 times 20 = 760

1520-760=760

Answer: 1520 square feet

Step-by-step explanation: Find the area of the triangle on the right. The bases are 38 and 40. Use the formula 1/2(l*w). 38*40=1520. 1520/2=760.

Next find the area of the triangle on the left. Since it's a parallelogram, both the top and bottom will be the same, so the other base is 40 ft. This also means that the area will be the same, so its area is also 760.

Finally add up the areas of the two triangles. 760+760=1520.

Gina was earning $10 per hour. THen she recieved a 10% pay increase. Next month, her pay rate will decrease by 10%. What will Gina's pay rate be next month? a. $10.10 per hour b. $12.10 per hour c. $9.90 per hour d. $10.00 per hour. Im thinking it would be c or d. PLEASE EXPLAIN?!

Answers

Third month Gina's payrate will be $9.9 per hour.

Given that,

  • Currently earning $10 per hour.
  • Second month increase by 10%.
  • Next month  decrease by 10%.

According to the given data, calculation of the given data are as follows,

Second month earning = $10 + ( $10 * 10%)

= $10 + $1

= $11 per hour

Third month's earning = $11 - ( $11 * 10%)

= $11 - $1.1

= $9.9 per hour

So, third month pay rate will be $9.9.

So you start with $10, you calculate the 10%, then add it to it. This is the second month's pay. Now you have to calculate the 10%, then subtract this from the second month's pay. 

10% of $10 = $1
Second month's earning = $10 + $1 = $11
10% of $11 = $1.1
Third month's earning = $11 - $1.1 = $9.9
