A contractor purchases 4 dozen pairs of padded work gloves for $53.76. She incorrectly calculates the unit price as $13.44 per pair for the expense report. What is the correct unit price. What is the error

1. The correct unit price of a pair = $1.12.

2. The error is taking the unit as 4 units instead of 48 units.

Step-by-step explanation:

a) Data and Calculations:

Cost of 4 dozen pairs of padded work gloves = $53.76

Each dozen pairs of the padded work gloves = $13.44 ($53.76/4)

Each pair of the padded work gloves = $1.12 ($13.44/12 or $53.76/48)

b) A dozen is made up of 12 units of something.  A dozen is an accepted unit of measurement that has persisted since time immemorial.  It originated from the practise of counting numbers in 12 instead of the current number system of 10.

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.
