To answer the question let x be the amount of money James will have after he sees Rita. If it was him who owed Rita $12 and he intent to pay, he will have $42.80 - $12 after seeing her. However, if it was Rita who owed him the amount, the money he will have after seeing her will be $42.80 + $12. Thus, the equations are,
x = 42.80 - 12 and x = 42.80 + 12
For this case we can make the following rule of three:
23000 -------> 100%
x --------------> 180%
Clearing the value of x we have:
x = (180/100) * (23000)
x = 41400
Answer:
you would expect about:
a) 41,400 responses
300.50 + 0.07x > = 900.85
0.07x > = 900.85 - 300.50
0.07x > = 600.35
x > = 600.35 / 0.07
x > = 8576.43 <=== she would have to sell at least 8576.43
Let

be a rectangular

matrix with column vectors

, i.e.

Then we have

and the product of the two is

Because the columns of

are orthonormal, we have

which means

reduces to an

matrix with ones along the diagonal and zero everywhere else, i.e.

where

denotes the identity matrix. This means the solution to

is given by
