Answer:
8%
Step-by-step explanation:
let,
this year population of students (pt)= 195
last year population of students (p)= 210
time(t)= 1 year
Population Change( R)= ?
we have,
pt= p( 1 - R/100)^t
195 = 210 ( 1 - R/100)^1
0.92= 1 - R/100
0.92-1= R/100
- 0.08 = - R/100
R= 0.08×100
R= 8%
40% off means she is paying 60% of the original price:
60 x 0.60 = 36.00
The sale price is $36
Now add the tax:
36 x 1.06 = 38.16
She pays $38.16 total
X is 5
y is 2
you just have to add what the translation was
