Kaitlin makes $13.15 per hour. If she works more than 40 hours in a week, she gets paid time and a half. Kaitlin gets a paycheck
Dmitrij [34]

Answer: 8 hours

Step-by-step explanation:

The pay is for 2 weeks which means that she worked for 80 hours.

At 80 hours, the regular income she should make is:

= 80 * 13.15

= $1,052

The total she made from overtime is therefore:

= 1,209.84 - 1,052

= $157.84

When she works overtime, she gets paid at a rate of a time and half. This means she gets:

= 13.15 * 1.5

= $19.73

The hours of overtime she worked is therefore:

= 157.84/19.73

= 8 hours

The C(x) equation is a parabola with a squared "x" and a positive leading term coefficient, meaning, is a vertical parabola and it opens upwards

the lowest point, or lowest cost value, it reaches, is the U-turn point, or vertex

\bf \textit{ vertex of a vertical parabola, using coefficients}\\\\&#10;\begin{array}{llccll}&#10;y = &{{ 1}}x^2&{{ -320}}x&{{ +40052}}\\&#10;&\uparrow &\uparrow &\uparrow \\&#10;&a&b&c&#10;\end{array}\qquad &#10;\left(-\cfrac{{{ b}}}{2{{ a}}}\quad ,\quad  {{ c}}-\cfrac{{{ b}}^2}{4{{ a}}}\right)

so, the lowest cost is at   \bf {{ c}}-\cfrac{{{ b}}^2}{4{{ a}}}

Ronny is selling coffee mugs for $3.50. So far, he has earned $301.00. Ronny needs to earn more than $371.00 in order to meet hi
mestny [16]
The easiest way to solve for this is to first find out how many he has sold right now. The way to find it is to divide the total amount of money (301) by the amount of each cup. (301/3.50) That should be equal to 86 cups. Now, you want to find the rest he needs to sell. The easiest way is to divide the number you want (371) by the number of each cup (371/3.50) That should be equal to 106. Since you want to know how many more he needs to sell you now need to subtract them. (106-86) That is equal to your answer, 20.
