Jason had $32. He spent all the money buying four CDs for x dollars each and two magazines for y dollars each. If Jason had boug

ht five CDs and two magazines, he would have run short by $4. The following system of equations models this scenario:
4x + 2y = 32
5x + 2y = 36

Use the system of equations to solve for x and y.

Answer:

(4,8)

Step-by-step explanation:

We have the two equations:

$ 4x + 2y = 32 \hspace{15mm} .....(1) $ and

$ 5x + 2y = 36 \hspace{15mm}  .....(2) $

Subtracting (1) from (2):

⇒ 5x + 2y -4x - 2y = 36 - 32

⇒                  x = 4

Substituting the value of x in (1), we get:

4(4) + 2y = 32

⇒ 2y = 16

⇒                      y = 8

We write the solution in ordered pair as (x,y) = (4,8).

Anthony's Nuffin Shop recently sold 4 blackberry muffins and 6 other muffins. Considering
Mazyrski [523]

Answer:

8

Step-by-step explanation:

In total, Antony sold 10 muffins. We can do a ratio like this:

\frac{4}{10} = \frac{x}{20}

Because there are 4 blackberry muffins. We solve.

Because 10 is directly half of 20, we can just multiply 4 by 2 because if you multiply 10 by 2, you'd get 20. 4 times 2 is 8. That's the answer.
