Joanne works two jobs to pay for college. She tutors for $25 per hour and also works as a receptionist for $12 per hour. Due to

il63 [147K]

Answer: C. $t+r\leq 25$

$25t+12r\geq 200$

Step-by-step explanation:

If 't' represents the number of hours Joanne tutors and 'r' represents the number of hours she works as a receptionist.

Then the total hours she can work=t+r

Since she can work up to 25 hours.

Thus $t+r\leq 25$

If she earns $25 per hour by tuition and $ 12 per hour by working as a receptionist .

Then her total earning =$ $25t+12r$

Since she must earn $200.

Then $25t+12r\geq 200$ .

Therefore, the required system of inequality will be

$t+r\leq 25$

$25t+12r\geq 200$

To find a slope we have to use this equation:
(y2 - y1 )/(x2 - x1)
and we have two x's and y's
so we will put them in their places....so (1-(-5))/(4-2)
and we will get 6/2 which is 3
Its A.3
