Question

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?

Answer 1

$6.99 for each memory card.

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
