Maya runs a farm stand that sells raspberries and blueberries. Each pound of raspberries

30 pounds of raspberries and 50 pounds of blueberries

Step-by-step explanation:

Let's use b to represent blueberries and r for raspberries. Each pound of raspberries costs $1, so to find the total cost of raspberries we use 1r, which is just r. For blueberries, we do 3.25b.

r+3.25b=192.5

We also know that we can combine the numbers for 80 total pounds.

r+b=80

We can subtract the two equations we have made to eliminate the r and solve for b.

2.25b=112.5

We divide both sides by 2.25.

b=50

We know that r+b=80, so if b is 50 then r must be 30.

Have a wonderful day! :D

1) C because algebra includes letters and numbers

2) B because + means more or adding more

3) C because parenthesis means times and sum is for adding

4) A because 8 has to be less than
