If you bought 24 light bulbs, how much money would you save by buying the less expensive light bulbs?

with the more expensive light bulbs, the cost would be $155.52

with the less expensive light bulb, the cost would be $119.04

This means you would save $36.48

$3.84 is the amount you save by purchasing the cheaper lightbulbs when buying 24.

Step-by-step explanation:

Alrighty, so!

With this one, I broke down the price per lightbulb (divided the money by the amount of bulbs in the package).

$4.96/4= $1.24/bulb

$6.48/6= $1.08/bulb

I then multiplied that amount per bulb by 24

$1.24 x 24 = $29.76

$1.08 x 24 = $25.92

And subtracted the lower number from the higher number to get the answer.

$29.76-$25.92= $3.84

Hope this helps :D

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
