A bracelet cost $36 after a 25% discount find the original price

48

Step-by-step explanation:

Let original price be x

So we then reduce the price by 25%.

So what is 25% of x? Well, 25% is 25 percent. PERCENT is Latin: PER CENTout of 100. So 25 out of 100 is 25/100 --> 0.25.

So 0.25 of x means 0.25x. This is the amount we took off, to reduce the price.

So we had ORIGINAL less REDUCTION = new price

--> x - 0.25x = 36

--> 1x - 0.25x = 36

--> 0.75x = 36

--> x = 36/0.75

--> x = 48

Tell me if i am wrong?

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
