A delivery man earns $350 per week. He also earns 15% commission on any sales he makes. The function E(s) = 350+0.15s relates his sales, s, to his total weekly earnings, E(s). What were his sales, in dollars, the week he earned $432.50?

Answer:

$550

Step-by-step explanation:

You need the equation E(s) = 350 + 0.15s, where E(s) represent his total weekly earnings.

If he earned $432.50 this means E(s) = 432.50 and you can write it as:

350 + 0.15s = 432.50 and this is the equation we need to solve

You need to substract 350 on both sides of the equation

350 - 350 +0.15 s = 432.50 - 350

And we get

0.15s = 82.5

Then we divide both sides of the equation by 0.15

0.15s/0.15 = 82.5/0.15

And we get s = 550.

-17 + n/5 = 33. solve this please

For this case we must solve the following equation:

Adding 17 to both sides of the equation we have:

Multiplying by 5 on both sides of the equation:

Thus, the value of n is 250

You and your friend are selling tickets to a charity event. You sell 8 adult tickets and 6 student tickets for $126. Your friend sells 12 adult tickets and 13 student tickets for $209. What is the cost of a student ticket?

S=cost per student ticket

a=cost per adult ticket

value=(students vlue)+(adults value)

student value=(cost per student) times number of students

adult value=(cost per adult) times number of adults

you sell 8 adult and 6 students and that is a value of 126

8a+6s=126

friend sell12 adult and 13 student and get 209

12a+13s=209

so we have

8a+6s=126 and

12a+13s=209

it might help to simplify the first equaiton by dividing by 2

4a+3s=63

we have

4a+3s=63

12a+13s=209

multiply first equaton by -3

-12a-9s=-189

add to secont equaiton

12a+13s=209

-12a-9s=-189 +

0a+4s=20

4s=20

divide 4

s=5

each student ticket costs $5.00

a=cost per adult ticket

value=(students vlue)+(adults value)

student value=(cost per student) times number of students

adult value=(cost per adult) times number of adults

you sell 8 adult and 6 students and that is a value of 126

8a+6s=126

friend sell12 adult and 13 student and get 209

12a+13s=209

so we have

8a+6s=126 and

12a+13s=209

it might help to simplify the first equaiton by dividing by 2

4a+3s=63

we have

4a+3s=63

12a+13s=209

multiply first equaton by -3

-12a-9s=-189

add to secont equaiton

12a+13s=209

-12a-9s=-189 +

0a+4s=20

4s=20

divide 4

s=5

each student ticket costs $5.00

Change the fraction into a decimal:

Divide the decimal by 100:

Change the fraction into a decimal:

Divide the decimal by 100:

3/8

= (3/8)* (100/100)

= (3/8*100)/100

= 37.5/100

= 37.5%

The correct answer is C. 37.5%~

= (3/8)* (100/100)

= (3/8*100)/100

= 37.5/100

= 37.5%

The correct answer is C. 37.5%~

Lesson 7.3 simplifying algebraic expressions Peggy bought 2 racing cars for 5x dollars each and 3 model motorcycles for 3x dollars each. Find the amount of money Peggy paid in terms of x.

Answer: $19x

Step-by-step explanation:

If she bought 2 racing cars,

= $5x +$5x = $10x (Because one car is 5x)

And if she bought 3 motor cycles,

= $3x + $3x $3x = $9x

Now we get our total amount = $10x + $9x = $19x
