A clothing design company pays two different people to design its T-shirts.
The company pays person A $8 an hour and pays person B $12. Person A
cannot work more than twice as many hours as person B, but they cannot
work more than 20 hours total. Person A makes the company a profit of $10
an hour, and person B makes the company a profit of $20 an hour. If the
company wants to make at least $150 in profit, which value will minimize the
cost to the company? (Each point is (a, b), where a is the hours person A
works and b is the hours person B works.)

A. (13.33, 6.67)
B. (7.5, 12.5)
C. (0,20)
D. (0, 7.5)

step-by-step explanation:

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

there are 25 people coming to the party

step-by-step explanation:

the text says that there will be 22 children at this party, 1 teacher, and 2 parents. so if you add them all together (22+1+2) it will equal 25. (=25)
