There are 40 pupils in a class. 75% of them are present. How may are present? How many are absent? with solution please :D

40, 70% present means 28 present , mean 40 - 28 = 12 absent

think like this

70% present means 30% absent —— 30% of 40 = 12 absent

THANK MY ANSWER AND MARK ME AS BRAINLIST

30 are present 10 are absent

Step-by-step explanation:

75%=3/4

so 3/4 of them are absent

3/4(40)=30

and 40-30=10 are absent

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300
