Calculate the percentage change in the cost of manufacturing the kitchen cabinet. State whether it is an increase or a decrease.​

Respuesta :

Using proportions, the percentage change in the cost of manufacturing the kitchen cabinet was a increase of 5.5%.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The standard cost is given as follows:

S = 250 + 120 + 60 = $430.

After the increases, the price will be given as follows:

S = 250 x 1.1 + 120 x 1.08 + 60 x 0.82 = $453.8.

The price increased. The percent change, given by the change divided by the initial value, is:

P = 23.8/430 x 100% = 5.5%.
