Can someone tell me if my answer for question two is wrong or not and why (brainiest)

Cheryl writes 7 fewer posts than Kevin on a social media site.

Answer the questions to write an algebraic expression. Then evaluate the expression for the given value.

1. Choose a variable to represent the number of posts Kevin writes.

variable: x

2. Which operation (addition, subtraction, multiplication, or division) applies to this situation? Justify your choice.

Subtraction

Cheryl’s post is less than Kevin’s

3. Use your variable and the operation you identified to write an expression for the number of posts Cheryl wrote.

Cheryl’s number of posts: x - 7

4. If Kevin wrote 21 posts, how many did Cheryl write?

x = 21

21-7 = 14

So, Cheryl wrote 14 post on her social media site.

Step-by-step explanation:

step-by-step explanation:

so first find out how much each is worth.

quarter= 25 cents

dime= 10 cents

pennies= 1 cent

then multiply each by how much each is worth.

200                     150                   300

x                         x                     x   1

  25                       10              

                                  300

1000                     1500

+                          

4000                                      

5000                                  

then count 2 from the back and add a period.

$50.00

$15.00

$3.00

and then add them

  $50.00

+

  $15.00

+

    $3.00

$68.00

so sunghee has $68.00
