Well, what is 6% of "v"? well, 6% of anything is just 6/100 * anything, so 6% of v is just 6/100 * v or 0.06v
so, v + 0.06v is just 1.06v <--- that'd be the increased price for <1900, 950>
well, what's that vectors wise? < 1900 * 1.06 , 950 * 1.06 >
that is <2014 , 1007>
now.. the Revenue is just price * quantity
so, I take it, it's just asking for the dot product of <2014, 1007> • <2700, 3700>
which should just be (2014 * 2700) + (1007 * 3700)
The total money with them was $100 in their accounts
