Given intercharges : 

Signs + and x and numbers 4 and 5.

  • A.5 x 4 + 20 = 40
  • B.5 x 4 + 20 = 85
  • C.5 x 4 + 20 = 104
  • D.5 x 4 + 20 = 95

Answer: C

Correct answer: 5 x 4 + 20 = 104

Exchanging the signs + and ×, and the numbers 4 and 5, turns the left side into \( 4 + 5 \times 20 \), which is \[ 4 + 100 = \mathbf{104} \]
