Answer:

92

Step-by-step explanation:

Let x be the additional number.

Therefore Reuben score will be

70, 75, 83, 80 and x.

From the question, we were told that the next mark will make Reuben to have an average of 80. This can be illustrated below:

Mean = sum of marks / numbers of mark

Mean = 80

Number of mark = 5

80 = (70 + 75 + 83 + 80 + x) / 5

80 = (308 + x) / 5

Cross multiply

308 + x = 80 x 5

308 + x = 400

Collect like terms

x = 400 — 308

x = 92

Reuben must score at least 92

Anni [7]

Answer:


Step-by-step explanation:
