First, we determine the area of the piece of cardboard by multiplying its dimensions.
area of cardboard = (8.5 inches) x (11 inches) = 93.5 in²
Then, we solve for the area of the cut out square,
area of the square = (4 inches) x (4 inches) = 16 in²
Then, we subtract the areas giving us the area of the frame which is equal to,
77.5 in²
Let the amount of dollars in goods sold be x, then her earning is 1850 + (4/100)x = 1850 + 0.04x.
For her to earn more than $2300, we have:
1850 + 0.04x > 2300
0.04x > 2300 - 1850
0.04x > 450
x > 450 / 0.04
x > $11,250
