Step-by-step explanation:

Sorry, because of lack of punctuation and organization, I cannot determine with any confidence the price per kilo of each of the rices.

He will spend the price of one kg of African rice plus twice the price of Basmati rice.

African rice = $1.69/kg

and

Basmati rice = $3.05/kg

THEN

Cost = 1.69 + 2(3.05) = $7.79

The norm of a vector $\vec x$ is equal to the square root of the inner product of $\vec x$ with itself.

a. $\|(-1,2)\|=\sqrt{\langle(-1,2),(-1,2)\rangle}=\sqrt{4(-1)^2+9(2)^2}=\sqrt{40}=2\sqrt{10}$

b. $\|(3,2)\|=\sqrt{\langle(3,2),(3,2)\rangle}=\sqrt{4(3)^2+9(2)^2}=\sqrt{72}=6\sqrt2$
