Question

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

Answer 1

$127.35 - $6.06 = $121.29
$91.98 ÷ 6 = $15.33
$121.29 - $91.98 = $29.31
$29.31 - $15.33 = $13.98
$13.98 ÷ 2 = $6.99

The answer is $6.99
