The price of a video game increases by 20%, then decreases by 10%. If the final price is $46.98,
Elena-2011 [213]

Answer:

The original price was $43.50

Step-by-step explanation:

Let

x ----> the original price of a video game

we know that

1) The price of a video game increases by 20%

so

100\%+20\%=120\%=120/100=1.20

The final price is equal to the original price multiplied by 1.20

so

1.20x

2) The price of a video game decreases by 10%

so

100\%-10\%=90\%=90/100=0.90

The final price is equal to the price at this moment multiplied by 0.90

so

0.90(1.20x)=1.08x

we have that

1.08x=46.98

solve for x

x=46.98/1.08\\x=\$43.50

A health clinic dietician is planning a meal consisting of three foods whose ingredients are summarized as follows: One Unit ofF
aleksley [76]

Answer:

z (min) = 360      x₁  =  x₃ = 0   x₂ = 3

Step-by-step explanation:

                             Protein      Carbohydrates    Iron      calories

Food 1  (x₁)               10                       1                   4              80

Food 2 (x₂)               15                       2                  8              120

Food 3 (x₃)               20                       1                  11              100

Requirements         40                        6                 12

From the table we get

Objective Function z :

z  =  80*x₁   +  120*x₂   +   100*x₃     to minimize

Subjet to:

Constraint 1.  at least 40 U of protein

10*x₁  +  15*x₂ + 20*x₃  ≥  40

Constraint 2. at least  6 U of carbohydrates

1*x₁  +  2*x₂  + 1*x₃    ≥  6

Constraint 3.  at least  12 U of Iron

4*x₁   +  8*x₂  +  11*x₃  ≥  12

General constraints:

x₁    ≥  0     x₂   ≥  0    x₃   ≥  0    all integers

With the help of an on-line solver after 6 iterations the optimal solution is:

z (min) = 360      x₁  =  x₃ = 0   x₂ = 3

The value of a mountain bike Y(in dollars) can be approximated by the model Y=200(1-.0025) to the t power, where T is the number
tino4ka555 [31]

Answer:

It will take 554 years

Step-by-step explanation:

Here, we want to estimate the time when t will be $50

We can rewrite the exponential equation as;

y = 200(1-0.0025)^t

In this case, y = $50 and we want to calculate t

so, we simply proceed to substitute the value 50 for y

we have this as ;

50 = 200(1-0.0025)^t

50/200 = (1-0.0025)^t

1/4 = 0.9975^t

0.25 = 0.9975^t

Take the natural logarithm of both sides

ln 0.25 = ln 0.9975^t

ln 0.25 = t ln 0.9975

t = ln 0.25 / ln 0.9975

t = 553.8 = 554 years

The bike will be $50 in 554 years
