Answer:

12.5 hours

Step-by-step explanation:

the student worked one extra day, so they'll get an extra 15.

use this formula

h=hours

8h+15=115

8h+15-15=115-15

8h=100

8h/8=100/8

h=12.5

Answer:

s = -2400t + 17400

Step-by-step explanation:

Let's say t is the x value on a coordinate plane, and s is the y. Then, we have the points (0, 17400) and (6, 3000). The slope of these is 14400/-6 or -2400.

Now we just have the equation y = -2400x + b, and from the point (0, 17400) we can find that b is 17400. So, we have y = -2400x + 17400. Convert these back into t and s and you get your answer, s = -2400t + 17400.
