Ответ:
D
Step-by-step explanation:
Since 1 and c are supposed to be equal, I put 2.35+0.25x=1.75+0.4x and solved that for the x. I got 4. Then, since I want to find the price of the beef, I plugged the 4 in the equation of "b" and got 3.35.
I made many mistakes when solving so I restarted many times which is why it took so long to answer. Whew, I actually found the answer though!
If you want to help, mark me brainliest, I'm only 1 away from getting virtuoso! That would make my day, and hope I made yours.
Bye!
