Answer 1

1st Question

A. 85

2nd Question

B. 71

Explanation:

1st Question

{90 + 94 + 96 + 90} = 370/4 = 92.5

{95 + 99} = 194/2 = 97

{87 + 75 + 82 + 85} = 329/4 = 82.25

{71} = 71/1 = 71

.20(92.5) +.25(97) +.30(82.25) +.25(71) = 85.175 Rounded-up = 85

2nd Question

.10(95) +.20(80) +.50(67) +.20(60) = 71

Answer 2

I got 71%, by finding out the individual percents and adding them up. Don’t know if that’s how you solve it, but it’s an answer choice, so makes enough sense to me.
