Add up the total number of pounds.
78 pounds
To find out how many pounds of fudge were sold, we can set up an equation based on the given information.
Let's assume:
x = pounds of chocolate fudge sold
y = pounds of vanilla fudge sold
According to the problem, 40 pounds of chocolate fudge were sold, so x = 40.
We know that chocolate fudge is sold for $2.15 per pound, and vanilla fudge is sold for $1.90 per pound. Therefore, the total amount made from selling chocolate fudge is 40 pounds multiplied by $2.15, which is 40 * 2.15 = $86.
Similarly, the total amount made from selling vanilla fudge is y pounds multiplied by $1.90, which is y * 1.90 = $1.90y.
Adding the amounts made from selling chocolate and vanilla fudge should give us the total amount made: $86 + $1.90y = $158.20.
Now we can solve the equation for y:
$86 + $1.90y = $158.20
Subtract $86 from both sides:
$1.90y = $72.20
Divide both sides of the equation by $1.90:
y = $72.20 / $1.90
y ≈ 38
So, approximately 38 pounds of vanilla fudge were sold.
To find out the total pounds of fudge sold, we can simply add the pounds of chocolate and vanilla fudge:
Total pounds of fudge sold = pounds of chocolate fudge + pounds of vanilla fudge
Total pounds of fudge sold = 40 + 38 = 78 pounds
Therefore, 78 pounds of fudge were sold.
