A contractor purchases 3 dozen pairs of padded work gloves for $41.40. He incorrectly calculates the unit price as $13.80 per pair for the expense report. What is the correct unit price? What is the error?

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft

0.038
