07:10 = 7:10 AM
17:30 = 5:30 PM
n + q = 35
n = 35-q
0.05n + 0.25q = 8.15
0.05(35-q) +0.25q = 8.15
1.75 -0.05q + 0.25q =8.15
1.75 + 0.20q = 8.15
0.20q = 6.40
q = 6.40 / 0.20 = 32

Answer:
You scored more than 80 %
Step-by-step explanation:
21/25
We need to change this to a decimal, then to a percent
21/25 *4/4 = 84/100
This is out of 100 so it is 84%
84>80.
You scored more than 80 %
