In the equation below, b and c represent the price per pound, in dollars, of beef and chicken, respectively, x weeks after july
Bumek [7]

Answer:

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!

Team, you have the opportunity to earn great bonuses this quarter. Your goal is to beat our competition, which brings in $1,800,
nikklg [1K]

They will have to bring in more than $600,000 a month to beat their competitors.

Step-by-step explanation:

Step 1; This establishment's competitors bring in $1,800,000 per quarter. This means that they bring in that amount of money through sales in a quarter of a year.

A quarter of a year = \frac{1}{4} × 12 months = 3 months.

So the competition brings in $1,800,000 in 3 months.

Step 2; Now we calculate how much this establishment must make to beat them.

Money to brought in a month = $1,800,000 / 3= $600,000 a month.              So the team must bring in more than $600,000 a month to beat their competitor's sales of $1,800,000 in a quarter.
