Danielle earns a 8.25% commission on everything she sells at the electronics store where she works. She also earns a base salary

Mariulka [41]

Answer: her sales last week was $4300.

Step-by-step explanation:

Let x represent her her sales in a week.

Danielle earns a 8.25% commission on everything she sells at the electronics store where she works. This means that the commission she gets if she makes sales of $x is 0.0825x

She also earns a base salary of $675 per week. The expression for the total earnings for a week in which she made sales of $x would be

0.0825x + 675

if her total earnings for last week were $1,029.75, it means that

0.0825x + 675 = 1029.75

0.0825x = 1029.75 - 675

0.0825x = 354.75

x = 354.75/0.0825

x = $4300

1. General Trades A roofer earns $24 per hour plus $36 per hour overtime. If he puts in 40 hours of regular time during a certai

snow_tiger [21]

Answer:

He should work $6\frac{2}{3}$ hours in overtime.

Step-by-step explanation:

Let x represents the number of hours of regular time and y represents the number of hours of overtime,

Since, earnings are $24 per hour for regular time and $36 per hour for overtime,

Thus, total earning = (24x + 36y) dollars,

Here, x = 40 hours and total earning = $ 1200,

By substituting the values,

1200 = 24(40) + 36y

1200 = 960 + 36y

240 = 36y

⇒ $y = 6\frac{2}{3}\text{ hours}$

Hence, he should work $6\frac{2}{3}$ hours in overtime.

PLEASE I AM BEGGING help me all I need to so is show work I have to turn this in tmrw pls

GenaCL600 [577]

Hello and Good Morning/Afternoon:

Let's take this problem step-by-step:

Let's consider all the information given:

Eddie's pension is based on the average of his last four year's salaries

$\hookrightarrow \text{average } = \text {sum of all salaries} / \text{ number of years}\\ \hookrightarrow \text{average}= 392000 / 4 = 98000$

2. The employer will pay 1.2% of that average for each year he worked

$\hookrightarrow \text{1.2 percent of average} = \frac{1.2}{100} *98000=1176$

3. The employer will therefore pay in total

$\hookrightarrow \text{Total pension} = 1176 * 20 \text{ years} = 23520$

Answer: $23520

Hope that helps!

Find the solution for y=2x-1 y=3x+2

ziro4ka [17]

ANSWER: (-3,-7)
Set them equal to each other so, 2x-1=3x+2 to find x. You should get x= -3

Then you plug in -3 for x to find Y for either y=2x-1 or y=3x+2. I’m picking y=3x+2 so when you plug in -3 to x it will be y=3(-3)+2 = -7 . So therefore y=-7
