Holly bought a sweater on sale for 38% off the original price. If she saved $67, what was the original price?

Leya [2.2K]

Answer:

If she saved 30% off the original price which is the same as saying she saved $18.00.

That means $18.00 is 30% of the original price.

Let x be original price of the sweater

.3x = 18

x= 18/.3

Ian puts 300.00 into an account to use for school expenses the account earns 6%interest compounded annually how much will be in

romanna [79]

This problem is about componded interest. The formula for compounded interest is:

$\begin{gathered} \text{Amount}=\text{Initial}\cdot(1+r)^t \\ \text{Where,} \\ \text{Amount is the total acumulative at time t.} \\ \text{Initial is the initial amount, at t=0} \\ r\text{ is the interest in decimal number.} \\ t\text{ is the time accordingly the interest, in this case is in years.} \end{gathered}$

In this case, Initial = 300, r = 0.06 and t=10 so the total amount in the account after 10 years is:

$\begin{gathered} \text{Amount}=300\cdot(1+0.06)^{10} \\ \text{Amount}=300\cdot1.06^{10} \\ \text{Amount}=300\cdot1.79085 \\ \text{Amount}=537.255 \end{gathered}$

The amount after 10 years is 573.26.

The area of a parallelogram is modeled by the formula, A = lw. Solve the equation for w.

erastovalidia [21]

Hello there! Thank you for asking your question here at Brainly! I will be assisting you with answering this question today, and will teach you how to handle it on your own in the future.

First, let's look at our problem.
"A = L * W, solve for W."

This is basic algebra, but I will teach you how to tackle this problem, so you can do it on your own.

So, we have the following equation:
A = L * W
To solve for W, we need to get it alone on one side of the equation. Currently, it is not alone, but rather is being multiplied by L.
To isolate W, we need to perform the opposite order of operations on both sides of the equation.

A = L * W
Divide both sides by L to isolate and solve for W.

W = $\frac{A}{L}$ is our solution.

The following equation matches the answer choice "C".

Your answer is "C."

I hope this helps!
