2. It's correct.
Step-by-step explanation:
price: $105
discount: 30%
tax: 8%
Calculate 30% of 105 and subtract it from 105
To convert 30% to decimals, divide by 100.
105-0.30(105)
105-31.50
$73.50
Now calculate 8% of it and add it.
73.50+0.08(73.50)
73.50+5.88
$79.38
teacher has 0.4 L of sea water , it means 0.4*1000 ml = 400 ml of sea water , she has.
Now every student has 5 ml spoon with them and there are a total of 20 students.
The teacher has asked every student to put 2 spoons of seawater into their container .
Now 1 spoon = 5ml
2 spoon = 10 ml
22 students are there it means
there are 44 spoons.
44 spoons = 44* 5 ml = 220 ml
It means Student put 220 ml seawater in total
And Teacher had 400 ml.
Now , Teacher is left with = 400 - 220 = 180 ml
3/10 because 30 of 100 is 30/100 and didve by 10 and you get 3/10
