Question 983331
Hi,
Please, note that * means dot
V*w=(260i+300j)*(2.50i+2.65j)
multiply term by term,
V*w=650+795
V*w=1445
 In pratical term,the number of gallon V of the gas sold is a fuction of the price W of the gas.
 The answer reveals that if the component price of a gallon of a gas increase,the number of the gas decrease.     Hope this helps;
