A violin was on sale of 50% off. The sale price
is $50. What was the original price?

Answers

Let us assume the original price of the violin to be = x
Sale price of the violin after discount = $50
Percentage of discount given on the violin = 50%
The
(50/100) * x = 50
x/2 = 50
x = 50 * 2 dollars
= 100 dollars
So the original price of the violin was $100. I hope the procedure is clear enough for you to understand. You can always use this procedure for solving similar problems without the necessity of taking any external help.

The violin is 50% off so 1/2 off so you would do reverse operation so the price would double to get back to its original form so the original price is 100$

Find the value of X or Y so that the line through the points has the given slope. (X, 0) and (4,1); slope: 1/5

Answers

Point slope formula:
(y₂ -y₁) = m(x₂ - x₁)
(1 - 0) = $(1)/(5)$ (4 - X)
1 = $(4)/(5) - (1)/(5) X$
$(1)/(5) = -(1)/(5) X$

-1 = X

Describe a situation in your life when you need to know how to find a starting time

A situation I believe you would need to know how to find a starting time in your life is when you are heading to an event.For example, someone may tell you an event (such as a job interview) start 2 hours from now and the now is 4:00pm.
