Annette, Barb, and Carlita work in a clothing shop. One day the three had combined sales of $1480. Annette sold $120 more than B

Nikitich [7]

Answer:

The quantity sold by Annette was $600

The quantity sold by Barb was $480

The quantity sold by Carlita was $400

Step-by-step explanation:

Let

x ----> quantity sold by Annette

y ---> quantity sold by Barb

z ---> quantity sold by Carlita

we know that

$x+y+z=1,480$ ----> equation A

$x=y+120$ ----> equation B

$y+z=x+280$ ----> equation C

substitute equation C in equation A and solve for x

$x+(x+280)=1,480$

$2x=1,480-280$

$2x=1,200$

$x=\$600$

Find the value of y

$x=y+120$

$600=y+120$

$y=600-120=\$480$

Find the value of z

$x+y+z=1,480$

$600+480+z=1,480$

$1,080+z=1,480$

$z=\$400$

therefore

The quantity sold by Annette was $600

The quantity sold by Barb was $480

The quantity sold by Carlita was $400

padilas [110]

Answer:

The tax Jenna and Richie pay on the gifts is $3.85.

Step-by-step explanation:

Given:

Cost of scarf = $12.45.

Cost of necklace = $35.65.

State tax charges sale tax = 8%.

Now, to find the sales tax paid on the gifts.

So, adding the price of the gifts:

$12.45+35.65=48.10$

Thus, the total amount of the gifts = $48.10.

Now, getting the sales tax the state charges:

$8\%\ of\ 48.10$

$=\frac{8}{100}\times 48.10$

$=0.08\times 48.10$

$=3.848$

The tax nearest to cent = $3.85

Therefore, the tax Jenna and Richie pay on the gifts is $3.85.

Solve the inequality. 5x - 7 < 8x + 8 The solution set is x |

timofeeve [1]

Answer:

- 5 < x

Step-by-step explanation:

To solve, we need to isolate the variable: x

5x - 7 < 8x + 8

Subtract 5x from both sides

5x - 5x -7 < 8x -5x + 8

- 7 < 3x + 8

Subtract 8 from both sides

- 7 -8 < 3x + 8 -8

-15< 3x

Divide both sides by 3

- 15/3< 3x/3

- 5 < x
