It’s really simple you can just type the equation into the calculator but it’s basically 8^3 which is 8 x 8 x 8 which is 512 and divide that by 2 which is 256 and add 9 which is 265.

Step-by-step explanation:

9 +  \frac{ {8}^{3} }{2}  \\ 9 +  \frac{8 \times 8 \times 8}{2}  \\ 9 +  \frac{512}{2}  \\ 9 + 256 \\ 265

The average daily sales at a bookstore was(7.6k + 2.2) dollars over a 4-day promotion.Find the total sales during the promotion.
dolphi86 [110]

Answer:

The total sales during the promotion is $69.6

Step-by-step explanation:

we are given

The average daily sales at a bookstore was(7.6k + 2.2) dollars over a 4-day promotion

we have to find total sales during 4 days

so, we can integrate it to find total sales

TS=\int _0^4\:\left(7.6k+2.2\right)dk

now, we can solve it

\int \:7.6k+2.2dk

=\int \:7.6kdk+\int \:2.2dk

=3.8k^2+2.2k

now, we can plug bounds

and we get

=69.6-0

TS=69.6

So,

the total sales during the promotion is $69.6
