Carly buys a gold ring priced at $273.00 if the sale tax is 10 % , how much will carly pay

Damm [24]

Hello!

<h2>Answer:</h2>

Carla will pay $300.30 for the gold ring.

<h2>Explanation:</h2>

Sales tax is added on to the total cost of the item. We need to figure out how much tax is on the ring.

To do that, we must calculate 10% (or 0.10) of $273.00.

273 × 0.10 = 27.3

Now, add the tax to the cost of the ring.

273 + 27.3 = 300.3

Identify the constant of proportionality for each direct variation below.

andriy [413]

Answer:

see explanation

Step-by-step explanation:

The equation of 2 quantities in direct proportion is

y = kx ← k is the constant of proportionality

y = - 4x ← in standard form

with k = - 4

$\frac{y}{x}$ = 2 ( multiply both sides by x )

y = 2x ← in standard form

with k = 2

$\frac{x}{y}$ = 3 ( multiply both sides by y )

x = 3y ( divide both sides by 3 )

$\frac{1}{3}$ x = y ← in standard form

with k = $\frac{1}{3}$
