let's say the amount is "x", hmmm how much is 27.4% of "x"? well

so then, we know that x - 0.274x = 1000

Estimated Answer=
Exact Answer= 
Step-by-step explanation:
Steady speed of the object =10 and one tenth km/h = 
Distance to be Covered=4 and nine tenths km =
km
To the nearest integer,
Steady speed of the object = 10 km/hr
Distance=5km

=
The estimated answer is 1/2 hr.
Next, we determine the exact answer.

The exact time taken is 
Answer:
9 OR 1
Step-by-step explanation:
Let the number be x
x² - 10x = -9
x² - 10x + 9=0
a=1
b=-10
c=9
Solve using the quadratic formula
x =9 or 1
<span>Ok. You would set up the problem like this: 32/x=64/100 and then cross multiply; 3200=64x; divide both sides by 64; x=50. Mary has 50 customers.</span>
