Question

help me please I only need question 18

Answer 1

Step-by-step explanation:

50x² + 250 = 40x² + 350

If the charge the same amount then the polynomials they use to determine their prices be equal

10x² + 250 = 350

subtract 40x² on both side

10x² = 100

x² = 10

Hence

x = 3.2

Answer 2

Answer:

x = 3.2
