Answer:
4 mL
Step-by-step explanation:
Multiply .25 by 2 because you are dispensing it twice a day.
.25 x 2 = .5, so you dispense .5 mL a day.
Now, multiply .5 mL a day x 8 days.
.5 x 8 = 4
Therefore, you should dispense 4 mL.
Answer:
Bag: 800/100 = 8*15 = 120
Umbrella: 400/100 = 4*15 = 60
120 - 60 = 60
The shopkeeper has gained 60 from the transaction
I’m pretty sure the answer is -1
