Step-by-step explanation:

Well first I subtracted the amount paid from the total cost and I got $390. to pay the rest in 3 equal payments I just divided it by 3 and got $130 I'm not completely sure but this is just how I solved it

Answer:

£130

Step-by-step explanation:

Assuming I understood your question correctly, you have a television which costs in full, £1290 including all applicable VAT and tax. You paid £900 up front, which lowers your overall cost to pay it back down to £390. The rest you pay over the course of an unknown time period in equal payments.

In a real-world scenario, we would take interest into account but you provided none so lets assume this is a utopia where credit needs no interest.

In which case we do simple division, of 390/3 which is a nice round 130.

Simple! You pay £130 per payment.

Joe borrowed $2,000 from the bank at a rate of 7% simple interest per year. How much interest did he pay in 5 years?
Bas_tet [7]
The simple interest formula is I = P * r * t

P is the principal (2,000)
r is the interest rate (7% or 0.07)
t is the time (5)

2000 * 0.07 * 5 = 700

$700.00 is the interest

Joe has to pay $700.00 in interest.

Hope this helps :D

A wholesaler requires a minimum of 4 items in each order from its retail customers. The manager of one retail store is consideri
Nataliya [291]

Answer:

  • It is the last graph: solid line, shaded area over the line x = 2 - x/2

Explanation:

1) <u>Set the algebraigic expression that represents the combinations of sofa and pillow orders:</u>

  • Number of sofas: x (given)
  • Number of pillows: 2y (given, since they come in pairs)
  • Number of items = number of sofas + number of pillows = x + 2y
  • Minimum of 4 items in each order (given) ⇒ x + 2y ≥ 4

<u>2) Predict the graph of the inequality x + 2y ≥ 4</u>

  • The border line is the equation x + 2y = 4
  • You can choose two points to draw a line
  • Choose the axis-intercepst:

        x = 0 ⇒ 2y = 4 ⇒ y =4/2 ⇒ y = 2 ⇒ point (0,2)

        y = 0 ⇒ x = 4 ⇒ point (4,0)

        Then the lines goes through (0,2) and (4,0) ... [the four graphs meet this]

  • The shading area is above the line because when you solve for y you get y ≥   2 - x/2, and the line is included because the "equal to" part of the symbol (≥ means greater than or equal to).

  •  To state that the line is included the graph uses a continous line instead of a dotted one.

<u>3) Conclusion:</u>

That means that the correct graph is the last one: solid line, shaded area over the line y = 2 - x/2.

Note: a more detailed graph would include the fact that the items cannot be negative, i.e. x ≥ 0 and y ≥ 0, which would result in that the shaded area would be on the first quadrant.
