Answer:
$18.15
Step-by-step explanation:
The total sales tax chargeable is:

We can now find the total amounts in taxes by multiplying the total tax rate by the pre-tax price,$220:

Hence, the total tax amount paid by Yuki is $18.15
Rose 40%
original=100%, now it is 140%
140% of original=now
140% of orignal=350
1.4 of original=350
divide both sides by 1.4
original=250
answer is C
other way
350/140=x/100
35/14=x/100
times both sides by 1400
3500=14x
divie both sides by 14
250=x
C is answer
Answer:
The positive numbers are 51 and 53
Step-by-step explanation:
Let first odd integer be x and another odd integer is (x+2).
According to the given condition,
The product of two positive consecutive odd integers is 2703 i.e.
x(x+2) = 2703

It is a quadratic equation. It can be solved as follows :
x = 51 and x = -53
Neglecting negative sign,
The first number = 51
Another number =(51+2) = 53
Hence, the positive numbers are 51 and 53.
1)
7/6d+4/3=-1/3
7/6d=-5/3
d=-5/3×6/7
d=-10/7
2)
5 1/2-u=9/4
11/2-u=9/4
22/4-u=9/4
13/4=u
3 1/4=u
3)
-m-7/8=-10
-m-7/8=-80/8
-m=-73/8
m=73/8 or 9 1/8
4)
2/7=4/5+9q
10/35=28/35+9q
-18/35=9q
q=-18/35×1/9
q=-2/35. Hope it help!
