Answer:
88
Step-by-step explanation:
this question is a question that involves the use of the statistical principles of finding average
let the summation of the six scores of the biology test be represented as ∑x
∴ ∑x÷ 6=74
∑x=74 × 6
=444
444 is the summation of all the scores of all the six biology scores reuben had
the next test would be his 7th
let y represent the score for the 7th test
therefore,
= 76
444 + y = (76 × 7)
444 + y = 532
y=88
Reuben needs to score 88 to raise his average to 76
