One saturday, a butcher sells a total of pounds of beef at $6.00 pound. she also sells some pork for $7.00 . on sunday, she sells pounds of beef again, but at the sale price of $4.00 per pound. she also sells some pork for $9.00given that she made the same revenue of ddd dollars each day, which of the following systems of equations can be used to find out how many pounds of beef, bbb, she sold each day?

6x₁ + 7y₁ = ddd

4x₂ + 9y₂ =ddd

Step-by-step explanation:

Let's call x₁ the pounds of beef sold on saturday and we call y₁ the pounds of pork sold on saturday. We will also call x₂ the amount of pounds of beef sold on sunday and y₂ the amount of pork sold on sunday. And we call ddd the revenue made each day, we know that both days the butcher made the same revenue.

We would have these equations:

6x₁ + 7y₁ = ddd

4x₂ + 9y₂ =ddd

the amount you'd have after the work is $1.55

step-by-step explanation:

you subtract 95% from $31.
