A hospital bill is estimated to be $480,000. It ends up actually costing the patient $524,50. What percent of error is in the bill? Round to the nearest tenths place.

8.5 %

Step-by-step explanation:

The formula used her :

\text{Percent error }=\dfrac{|\text{Estimated value-Actual value}|}{\text{Actual value}}\times100Percent error =

Actual value

∣Estimated value-Actual value∣

×100

Given : A hospital bill is estimated to be $480.00 it ends up actually costing the patient $524.50 .

Then, the percent of Error in the bill will be :

\begin{gathered}\text{Percent error }=\dfrac{|480-524.50|}{\text{524.50}}\times100=\dfrac{|-44.5|}{524.50}\times100=\dfrac{44.5}{524.50}\times100=8.48427073403\approx8.5\%\end{gathered}

Percent error =

524.50

∣480−524.50∣

×100

=

524.50

∣−44.5∣

×100

=

524.50

44.5

×100

=8.48427073403≈8.5%

[Rounded to the nearest tenth]

Hence, the percent of Error in the bill = 8.5%

e) none of the above because the measure of angle cba is 101°

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
