A General Motors buyer-incentive program offered a 5.5% rebate on the selling price of a new car. What rebate (in dollars) would
Mashcka [7]

Answer: he would receive a rebate of $1677.5

Step-by-step explanation:

A General Motors buyer-incentive program offered a 5.5% rebate on the selling price of a new car. This means that if the selling price of the new car is $x, the rebate (in dollars) that a customer would receive is

5.5/100 × x = 0.055 × x = 0.055x

Therefore, for a customer who purchased a $30,500 car under this program, the rebate that he would receive is

0.055 × 30500 = $1677.5

Select the list that correctly includes all of the coefficients from the problem
matrenka [14]

Answer:

( B.) 6, 1, -2 , -4

Step-by-step explanation:

A coefficient is a number multiplied by a variable. So, in this case let's take a look at the problem.

-2+6y+m-2y+8-4m

Now we have to find the numbers that have a variable next to it

which are 6,m,-2, and -4

(If you are wondering that why m is a coefficient its because it is also known as 1m)

Final answer = 6, 1, -2 , -4

Hope this helps!

Seventy concert tickets are sold for 550$.Each adult ticket cost 9$ and each children’s ticket cost 5$.Find the number of adult
Afina-wow [57]

50 adult tickets and 20 children tickets were sold for the concert.

Step-by-step explanation:

Given,

Number of concert tickets sold = 70

Revenue generated = $550

Cost of each adult ticket = $9

Cost of each child ticket = $5

Let,

x be the number of adult tickets sold

y be the number of child tickets sold

According to given statement;

x+y=70        Eqn 1

9x+5y=550    Eqn 2

Multiplying Eqn 1 by 5

5(x+y=70)\\5x+5y=350\ \ \ Eqn\ 3

Subtracting Eqn 3 from Eqn 2

(9x+5y)-(5x+5y)=550-350\\9x+5y-5x-5y=200\\4x=200

Dividing both sides by 4

\frac{4x}{4}=\frac{200}{4}\\x=50

Putting x=50 in Eqn 1

50+y=70\\y=70-50\\y=20

50 adult tickets and 20 children tickets were sold for the concert.
