Answer:

The correct option is 3.

Step-by-step explanation:

The given expression is

(7-3i)\cdot(2-i)

We need to find the simplified form of given expression.

Using distributive property, the given expression can be written as

7\cdot(2-i)-3i\cdot(2-i)

7(2)+7(-i)-3i(2)-3i(-i)

On further simplification we get

14-7i-6i+3i^2

14-13i+3(-1)               [\because i^2=-1]

14-13i-3

On combining like terms we get

(14-3)-13i

11-13i

The simplified form of given expression is 11-13i. Therefore the correct option is 3.

Bonita spent $8.94 on groceries. She bought a gallon of milk for $4.29 and 3pounds of sliced turkey. How much does 1 pound of sl
Vesna [10]
<h2>Information</h2>

$8.94 spent in total on groceries

Gallon of milk = $4.29

3 pounds of sliced turkey bought = ?


<h2>Explanation</h2>

Subtract the total amount spent on groceries with what items you have prices for (in this case the gallon of milk):

$8.94 (total spent) - $4.29 (gallon of milk) = $4.65 (for 3 pounds of sliced turkey)

Next, divide the price for 3 pounds of sliced turkey with however many pounds Bonita bought (in this case, 3 pounds):

$4.65 (total for 3 pounds of turkey) ÷ 3 (pounds of turkey) = $1.55 (per pound of turkey)


<h2>Solution</h2>

Each pound of turkey costs $1.55
