Mike is 19.
If you turn the question into an equation it turns to:
J x 2 - 3 = M
So since you don’t know Jasmine’s age you would use guess and check. 8,9, and 10 didn’t work but when you put in 11:
11 x 2 - 3 = M
22 - 3 = M
19 = M
And to check your work
J + M has to equal 30 so,
11 + 19 = 30
30 = 30
(12 - 9) / 12 = (40 - x) / 40
3/12 = (40 - x) / 40
40(1/4) = 40 - x
10 = 40 - x
10 - 40 = -x
-30 = -x
30 = x <=== percent decrease from 40 to 30
Answer:
C
Step-by-step explanation:
Gross taxable Income = $ 1,166
Rate of Income tax = 30%
Amount of income tax = 30 % of 1,166
= 
=$339.6
≅$340
Plug in n = 1 into the nth term formula
a(n) = 4n-1
a(1) = 4*1-1
a(1) = 3
So the first term is 3
The second term will be 7 because we add on 4 each time, as indicated by the slope of 4. This is also known as the common difference.
So the nth term is found by adding 4 to the (n-1)st term, in other words,
a(n) = a(n-1)+4
----------------------------------------------------------------------------
In summary, the answer is
a1=3; an=an-1+4
which is choice B
First month she payed 1451 dollars
Second month she payed 1/3 of that, which is:
1451/3 = 483.66
Third month she payed 1/3 of 483.66 because as text says, every next month she pays 1/3 of previous month payed amount.
483.66/3 = 161.22
Forth month she payed
161.22/3 = 53.74
In total she payed:
$2149.62 - B.
hope this helps :)
