1. Multiply the number of chairs sold by how much the chair costs. 27x50= $1350
2. Take away the answer you just got from the minimum profit. $8400-$1350= $7050
3. Multiply 300 until you get a number over or at $7050 and the amount of times you multiplied 300 is your answer
4. But if the number you got added to 27 is higher than 53 I don’t think there is a possible solution but I could be wrong.
