Answer:

y = -3x; the const. of prop. is -3.

Step-by-step explanation:

Recall:  a proportional relationship satisfies y = kx, where k is the constant of proportionality.

In this particular example we see that (-3)(-2) = 6, (-3)(1) = -3, and (-3)(2) = -6.

This confirms adherence to the equation of a proportional relationship.  The constant of proportionality here is -3.

The function governing the table is y = -3x.

the wholesale price for a pair of shoes is $5.50. A certain department store marks up the wholesale price by 40%. Find the price
Furkat [3]

EXPLANATION

Price of shoes = $5.50

Markup= 40%

Let's call x to the unknown final price.

The markup percentage relationship is given by the following formula:

\text{Markup =( }\frac{Selling\text{ Price}-\text{Cost Price}}{\text{Cost Price}})\cdot100

Replacing terms:

\text{40}=(\frac{x-5.5}{5.5})\cdot100

Multiplying both sides by 5.5:

40\cdot5.5=(x-5.5)\cdot100

Dividing both sides by 100:

\frac{40\cdot5.5}{100}=x-5.5

Adding 5.5 to both sides:

(\frac{40\cdot5.5}{100})+5.5=x

Simplifyng the fraction:

2.2+5.5=x

Adding numbers:

\text{7}.7\text{ = x}

Switching sides:

x=7.7

Answer: The final price of the shoes in the deparment store is $7.7

Snowcat [4.5K]
Simple...

Which line shows the first error in the solution?

Line 3

This said, because...

5x-25=15

It'd be adding not subtracting-->>

5x-25=15-25 (No)

5x-25=15
    +25  +25

5x=40 (Yes) 

Thus, your answer.
