Answer:

The location will be at - 28\frac{1}{8} units.

Step-by-step explanation:

A scuba diver descended at a rate of 2\frac{1}{4} units per second.

Now, if 0 represents the surface of the water and distances below the surface are negative, then after 12\frac{1}{2} seconds the location of the diver will be given by the followings :

In one second the diver descends by 2.25 units depth.

So, in 12.5 seconds the diver will descend by (2.25 \times 12.5) = 28.125 units i.e. 28\frac{1}{8} units depth.

Therefore, the location will be at - 28\frac{1}{8} units. (Answer)

Answer:

55 performances

Step-by-step explanation:

The first equation will be the total cost. The total cost has $88,000 already and then $5,900 is added with each performance. So the equation would be 88,000+5,900x because x will represent the number of performances.

y = 88,000 + 5,900x

The next equation will be how much the performances earn. If they earn $7,500 with each performance then the equation will be 7,500x, with x representing the number of performances

y = 7,500x

Now set the equations equal to each other and solve for x

7,500x = 88,000 + 5,900x

1,600x = 88,000

x = 55

They need to have 55 performances for the cost and the revenue to break even.
