A company sells cereal in two different-sized boxes: a 17-ounce box for $2.89, and a 24-ounce box for $3.29. How do the unit pri

garik1379 [7]

Answer: Last option.

Step-by-step explanation:

Let be "s" the unit price of the smaller box and "l" the unit price of the larger box.

According to the information given in the exercise, the smaller one is a 17-ounce box which costs $2.89. Therefore, in order to find the value of "s", you need to divide $2.89 by 17 ounces. This is:

$s=\frac{2.89\ dollars}{17\ ounce}\\\\s=0.17\ \frac{dollars}{ounce}$

You know that the larger box has 24 ounces and it costs $3.29.

Therefore, in order to find the value of "l", you need to divide $3.29 by 24 ounces. This is:

$l=\frac{3.29\ dollars}{24\ ounce}\\\\l=0.137\ \frac{dollars}{ounce}$

Finally, find the difference:

$0.17\ \frac{dollars}{ounce}-0.137\ \frac{dollars}{ounce}=0.033\ \frac{dollars}{ounce}$ or $3.3\ \frac{cents}{ounce}$

Therefore, you can conclude that the larger box is better buy because it is approximately 3.3 cents cheaper per ounce.

Given the sequence tn defined recursively below, find t4.

Alina [70]

Answer:

$t_4 = 20$

Step-by-step explanation:

The base case in the recursive function are:

$t_1 = 1$

$t_2 = 2$

The recursive case is equal to:

$t_n = 2t_{n-1} + 3t_{n-2}$

So replace $t_n$ for $t_4$ :

$t_4 = 2t_{3} + 3t_{2}$

In the new expression $t_2$ is a base case so you don't have to worry for that part, but $t_3$ is still the recursive case so evaluate again in $t_n$

$t_3 = 2t_{2} + 3t_{1}$

$t_2$ and $t_1\\$ are define as base cases so you replace for it's numbers:

$t_3 = 2(2) + 3(1) = 7$

Now return to $t_4$ and replace for the new values:

$t_4 = 2(7) + 3(2) = 14 + 6 = 20$

So the final answer is 20
