A company sells a mix of peanuts and cashews. For every 3 ounces of peanuts, there are 2 ounces of cashews. A batch has 60 ounces of peanuts. How many ounces of cashews will a batch have?

Answers

Answer:

Proportion states that the two ratios or fraction are equal.

As per the given statement: For every 3 ounces of peanuts, there are 2 ounces of cashews. A batch has 60 ounces of peanuts.

Let x be the ounces of cashew will a batch have.

then by definition of proportion, we have;

$(3)/(2) = (60)/(x)$

By cross multiply we have;

$3x = 120$

Divide by 3 on both sides we get;

$x = 40$

therefore, 40 ounces of cashews will a batch have for every 60 ounces of peanuts.

3:2 ratio 60:?

60 divided by 3 is 20

therefore 2 x 20 = 40

40 cashews

How much money will you have if you started with $1200 and put it in an account that earned 7.3% every year for 10 years?

Answers

So an exponential equation is gonna be used for this problem. The formula for such is $y=ab^x$ , in which the a variable is the initial value and the b variable is the growth/decay rate.

For this situation, 1200 is gonna be your a variable since you've started out with it. And as for your b variable, its gonna be 107.3%, or 1.073, since it's increasing.

Your equation should look like this: $y=1200(1.073)^x$ and from here just plug in 10 into the x variable and solve.

Multiply (1.073)^10 (don't round answers until the end), and take that answer and multiply it with 1200, your answer should be $2427.61.

$y=1200(1.073)^(10) \n y=2427.61$
