Carla bout a digital camera that cost $91.98. she also bought 2 identical memory cards and a camera case. the camera cost 6 times a much as the case. she paid $127.35, including sales tax of $6.06. what was the cost of each memory card?

$6.99 for each memory card.

Step-by-step explanation:

she paid a total of 127.35 for everything including sales tax.  

if the camera cost 6 times more than the case you will first divide 91.98 by 6

91.98/6 = 15.33 total cost of the case

so now you subtract your camera, case and sales tax from the total amount she paid which is 127.35

127.35 - 91.98 - 15.33 - 6.06 = 13.98 is left to find the price of each memory card you divide 13.98 by 2

13.98/2 = 6.99

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
