Your business uses the allowance method to account for uncollectible receivables. At the beginning of the year, Allowance for uncollectible accounts had a credit balance of $1,600. During the year you wrote off bad receivables of $2,000 and recorded Bad debt expense of $2,700. What is your year-end balance in Allowance for uncollectible accounts?

A. $2,300

B. $3,600

C. $4,300

D. $2,700

Your year-end balance in Allowance for uncollectible accounts is $2,700. The right answer is D

Step-by-step explanation:

According to the given data we have the following:

Allowance for uncollectible accounts had a credit balance =$1,600

recorded Bad debt expense =$2,700

written off=$1,600

Therefore, in order to calculate your year-end balance in Allowance for uncollectible accounts we have to make the following calculation:

year-end balance in Allowance for uncollectible accounts=Allowance for uncollectible accounts had a credit balance+recorded Bad debt expense- written off

year-end balance in Allowance for uncollectible accounts=$1,600+$2,700 -$1,600

year-end balance in Allowance for uncollectible accounts=$2,700

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
