Glad to help, but in my view "helping" means providing you with assistance only after you've begun your own efforts to solve these problems.

Look at    <span>3(k+5)=-2(3k-6).  Goal:  Solve for k.
Multiplying where indicated:

             3k + 15 = -6k + 12

Add 6k to both sides:         9k = 12 - 15

dividing both sides by 9:  k = -3/9, or    k = -1/3   (answer).

Please start one of the other solutions; ask if you have questions about it.</span>

Daniel works no more than 16 hours a week while attending college. He wants to spend at least 2 hours but no more than 10 hours
Vinvika [58]

Answer:

The maximum earning is $122

Step-by-step explanation:

The computation of the Daniel maximum earnings is as follows;

Since there is total of 16 hours

so 10 hours would be for parking cars and the remainig hours i.e.

= 16 hours - 10 hours

= 6 hours

This above hours for working at store

So,

= 10 hours × $8 + 6 hours × $7

= $80 + $42

= $122

Hence, the maximum earning is $122

Last year 300 people attended a play with ticket price of $8. The school estimates that 20 fewer people attend for each $1 incre
masya89 [10]

Answer:

$12

Step-by-step explanation:

If we stuck with the price of $8, then we end with an income of $2400

Increasing it by $1 will decrease attendance by 20

8 x 300 = 2400

9 x 280 = 2520

10 x 260 = 2600

11 x 240 = 2640

12 x 220 = 2640

13 x 200 = 2600

We're starting to go down, so let's stop there

The ticket price of $11 or $12 appears to give the most income

I would stick with $12 since your still getting more money from one ticket
