Answer:

a_{7}=\frac{256}{729}   or   a_{7}=0.35

Step-by-step explanation:

a_{n} =a_{1}* r^{n-1}

a_{7}=4*\frac{2}{3}^{7-1}

a_{7}=4*\frac{2}{3}^{6}

a_{7}=4*\frac{64}{729}

a_{7}=\frac{256}{729}

or

a_{7}=0.35

Answer:

C = 2000 + 25 * X

$ 7000

Step-by-step explanation:

We have that the value of the total costs is equal to the fixed costs plus the variable costs.

As fixed costs we have $ 2000 and variable cost we have $ 25 for each unit, that is, the equation for total costs would be:

Let x be the number of toys, then:

C = 2000 + 25 * X

If there are 200 toys, the cost would be:

Replace x with 200:

C = 2000 + 25 * 200

C = 7000

In other words, the cost of producing 200 toys would be $ 7000.
