A rental car company charges $77.50 per day to rent a car and $0.10 for every mile driven. Sydney wants to rent a car, knowing t

Zepler [3.9K]

Answer:

Owen can afford to keep and drive the car for 4 days.

Step-by-step explanation:

The total owing on the car rental is R(d) = ($77.25/day)d + ($0.12/mile)m ≤ $330. Substitute 1 for d (that is, the rental is for 1 day) and 175 for m:

R(d) = ($77.25/day)(d days) + ($0.12/mile)(175 miles) ≤ $330

= $77.25d + $21 ≤ $330

This simplifies to $77.25d + $21 ≤ $330, or

$77.25d ≤ $309

Solving this by dividing both sides of the above equation by $77.25, we get

d = ($309)/($77.25) = 4

Find the matrices of

aniked [119]

$\huge{\sf \left[{x-2y\atop 6x-2z}\:\:\:{4y-3\atop 2y-z}\right]=\left[{-3\atop 4}\:\:\:{5\atop 3}\right]}$

Creating equations

$\\ \sf\longmapsto x-2y=-3\dots(1)$

$\\ \sf\longmapsto 4y-3=5\dots(2)$

$\\ \sf\longmapsto 6x-2z=4\dots(3)$

$\\ \sf\longmapsto 2y-z=3\dots(3)$

From eq(2)

$\\ \sf\longmapsto 4y-3=5$

$\\ \sf\longmapsto 4y=5+3$

$\\ \sf\longmapsto 4y=8$

$\\ \sf\longmapsto y=\dfrac{8}{4}$

$\\ \bf\longmapsto y=2$

Put the value in eq(1)

$\\ \sf\longmapsto x-2y=-3$

$\\ \sf\longmapsto x=-3+2y$

$\\ \sf\longmapsto x=-3+2(2)$

$\\ \sf\longmapsto x=-3+4$

$\\ \bf\longmapsto x=1$

Put the value in eq(4)

$\\ \sf\longmapsto 2y-z=3$

$\\ \sf\longmapsto z=2y-3$

$\\ \sf\longmapsto z=2(2)-3$

$\\ \sf\longmapsto z=4-3$

$\\ \bf\longmapsto z=1$
