Answer:
Girls in Mr. Chang's class: 28 - 21 ; # girl students = # total students - # boy students ; 7 girl students.
Boys in Mr. Chang's class: 28 - 7 ; # boy students = # total students - girl students ; 21 boy students.
Four people read 6to 8 books.
If that’s meant to be x^2 - 6x - 16
Then factorise to (x+2)(x-8)
So x intercepts are -2 and 8
The original price is $88.
how I got the answer:
$22 • 100= 2,200
2,000/25= $88
regular shoes cost w/75% off is $66.00
how I got my answer:
$88 • 75% = 6,600
6,600/100 = $66.00
