What's the issue? You gave the possible answers but that's about it.
Answer:
625 cm3
Step-by-step explanation:
Formula V1 * P1 = V2 * P2
V1 = 450 cm3
P1 = 125 kPa
P2 = 90 kPa
V2 = ?
V2 = (V1 * P1) / P2
V2 = (450 cm3 * 125 kPa) / 90 kPa = 625 cm3

Mixing the two ingredients would be adding them together:
1/2 gram + 3/4 gram = 1 1/4 total grams
Divide the total grams by 1/8 to find the number of experiments they can do:
1 1/4 / 1/8 = 5/4 / 1/8 = 5/4 * 8/1 = 40/4 = 10
They can conduct 10 experiments.
Total points : 46
15% of 40 is 6
40 + 6 = 46
To double check:
46/40 = 1.15 = 115%
