The current cost of a box of cereal is $3.39. At the time of this writing, the CPI for cereal is 289.7. What was the cost of a box of cereal in 1983 to the nearest cent?

Answers

To solve this problem we have to first identify the data that we need and is important. You can arrange it like this:

Current Cost of Cereal: $3.39

CPI: 289.7

To find the cost of a box of cereal in 1983 we will need to use the following formula:

Cost in Base Year = Current Cost/CPI*100

Replace the data in the formula and we get the following:

1983 = 3.39/289.7*100

In 1983 the cost of a box of cereal was $1.170176044

Suppose the population of trout in a certain stretch of a river is 4000. In about how many years will the population of trout be 700 if the decay rate is 35%? Use the equation 700 = (4000)(0.65)x and round the value of x to the nearest year.

Answers

Answer: 4 years

Step-by-step explanation:

The exponential decay equation is given by :_

$y=A(1-r)^x$ , where A is the initial population and r is the rate of decay in x years .

The initial population of trout in a certain stretch of a river =4000

The rate of decay = 35% =0.35

To find the number of years (x) for the population of trout be 700, we put all the values of the above equation, we get

$700=4000(1-0.35)^x\n\n\Rightarrow700=4000(0.65)^x\n\n\Rightarrow (0.65)^x=(700)/(4000)\n\n\Rightarrow(0.65)^x=0.175\n\n\text{Taking log on both sides, we get}\n\n\Rightarrow x\log(0.65)=\log(0.175)\n\n\Rightarrow x(-0.187086643357)=-0.756961951314\n\n\Rightarrow x=(-0.756961951314)/(-0.187086643357)\n\n\Rightarrow\ x=4.0460502029\approx4\text{ years}$

4.97991230017 years is the final answer. I would suggest rounding your answer to the nearest tenth, so 5 years should be your correct answer.

Explain what the point (20,160) represents in the context of the situation? Check all boxes that apply A. 160 shirts cost $20B. 20 shirts cost $160
C. 20,160 shirts cost money
D. The total cost of shirts is 20,160

Answers

Answer:

option B is correct option.

Step-by-step explanation:

Explain what the point (20,160) represents in the context of the situation? Check all boxes that apply

Looking at the graph we come to know that 20 shirts cost $160 because x -axis represent number of shirts and y-axis represent Total Cost

So, the point(20,160) means x = 20 and y=160

We have 20 shirts and the cost is $160

So, option B is correct option.

a baseball team has won 15 games and lost 12 games. Based on the results, which is the best prediction for the number of wins the team will have if they play162 games

Answers

90
15 is 5/9 of 27... 90 is 5/9 of 162

games lost : games played --> games lost/games played

12/15 =?/162
cross multiply and divide. --> 12 x 162/15 =129.6
that means, they will lose about 130 games out of 162. therefore they will win about 32 games.
