$\%\text{error}=\dfrac{|\text{estimated value}-\text{actual value}|}{\text{actual value }}\cdot100\%\\\\\%\text{error}=\dfrac{|265-297|}{297}\cdot100\%\\\%\text{error}=\dfrac{|-32|}{297}\cdot100\%\\\%\text{error}=\dfrac{32}{297}\cdot100\%\\\%\text{error}\approx10.8\%$

You and your friend are selling tickets to a charity event. you sell 12 adult tickets and 6 student tickets for $138. your frien

mr Goodwill [35]

Let's say the cost of student tickets is x and the cost of adult tickets is y. Then:

(1) 12y + 6x = 138
(2) 5y + 11x = 100

If we rearrange equation (1) we get:
12y = 138 - 6x
Now divide each side by 12:
y = 11.5 - 0.5x

We can now substitute this into equation (2):

5(11.5 - 0.5x) + 11x = 100
57.5 - 2.5x + 11x = 100
8.5x = 42.5
x = 5, therefor the cost of a student ticket is $5.00

you bought your friends a heart shaped pound of chocolate caramels. You anticipate each chocolate was 50 calories. Each chocolat

Wittaler [7]

There was 25.37% error in calculations.

Step-by-step explanation:

Given,

Anticipated calories = Approx value = 50 calories

Actual calories = Exact value = 67 calories

Percent error = $\frac{|aprrox\ value-exact\ value|}{exact\ value}*100$

Percent error = $\frac{|50-67|}{67}*100$

Percent error = $\frac{|-17|}{67}*100=\frac{17}{67}*100$

Percent error = $\frac{1700}{67}$

Percent error = 25.37%

There was 25.37% error in calculations.

Define a variable and write an equation to model each situation. Then solve. Show your work. Tickets to the county fair for four

Citrus2011 [14]

If x is the childrens ticket
$4(x + 1.5) + 5x = 33.30 \\ 4x + 6 + 5x = 33.3 \\ 9x = 33.3 - 6 \\ 9x = 27.3 \\ x = \frac{27.3}{6} \\ x = 4.55$
so that means that the adults ticket is
$x + 1.50 = 4.55 + 1.50 = 6.05$
