I'd seriously appreciate it if anyone could asap! i'll be giving brainliest! mrs. johnson’s class sold cookies for $2.50 each and mr. smith’s class sold popcorn for $1.50 each. together, the classes sold 53 items and earned $105.50 for their school. write and solve a system of equations that models the problem and shows which class earned more money and how much more money did that class earn.

Solution:

Let number of Cookies sold by Mrs. Johnson’s class = x

Let number of Cookies sold by Mrs. Smith class = y

Total Number of Cookies sold by Mrs. Johnson’s class and  Mr. Smith’s class=53

Writing in terms of equation the statement which is given above

1. x + y = 53 ⇒y= 53-x

2. 2.50 x + 1.50 y = 105.50

Substituting the value of y, in equation 2, we get

⇒2.50 x + 1.50 (53-x)= 105.50

⇒ 2.50 x + 1.50 × 53 - 1.50 x= 105.50→→[Using Distributive property of addition with respect to multiplication]

Combining like terms using Operations (Addition, Subtraction)

⇒1. 0 x  + 79.50=105.50

⇒  x =105.50-79.50

⇒ x= 26

Putting the value of x, in equation (1)

26 + y=53

y= 53 - 26

y= 27

Money earned by Mrs. Johnson’s class = 26 ×  $2.50=$ 65

Money earned by Mr. Smith’s  class = 27 ×  $1.50=$ 40.50

So, Mrs. Johnson’s class earned more money.

Amount of money  that Mrs. Johnson’s class earned exceeds than Mr. Smith’s class= $ 65 - $ 40.50= $ 24.50

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
