please tell the answer with explation​

Answer 1

Answer:

Birth rate in the whole week {Average Births} = 35

Let total births in the week = x

$\frac{x}{7} = 35$

$x = 7(35)$

$x = 245$

Birth rate from Monday to Thursday {Average Births} = 32

Let total births in four days days = y (including births on Thursday)

$\frac{y}{4} = 32$

$y = 4(32)$

$y = 128$

Birth rate from Thursday to Sunday {Average Births} = 36

Let total births in 4 days = z (including births on Thursday)

$\frac{z}{4} = 36$

$z = 4(36)$

$z = 144$

Let the number of births on Thursday = T

245 = 128 + 144 - T

245 = 272 - T

T = 272 - 245

T = 27

The number of births on Thursday = 27
