Your number is 57.
Because....
47 + 10 = 57
67 - 10 = 57
Hope that helps!
No, he almost earns $400
9.20 / 1.5 = 6.13
9.20 - 6.13 = 3.07
9.20 + 3.07 = 12.27
12.27 x 2.25 = 27.61
9.20 x 40 = 368
368 + 27.61 = 395.61
Mr. Evans earned $395.61 for 42.25 hrs.
I’m confused on what you mean
number sof student of the group is 50
Step-by-step explanation:
let the number students be x
total bill is Rs 200
each student will pay =200/x
now 10 students do not have the money
so x - 10 students will pay the bill of Rs 200
according to the problem
=
+ 1
or,
-
= 1
or, 200 (
-
) = 1
or, 200(
) = 1
or, 200 X 10 = x(x-10)
or,
- 10x - 2000 = 0
or,
- 50x +40x - 2000 =0( using middle term factor)
or, (x - 50) (x+40) = 0
x = 50 ( x = -40 for number of students it is not possible)
