Answer:
The selling price is $294
Step-by-step explanation:
5/100 (280)
0.05 * 280 = 14
5% of 280 equals 14.

$14 + $280 = $294
<em>The selling price is $294</em>

Answer:
John has 9 baseball cards.
Step-by-step explanation:
To start off, we want to find the highest product of 12 without going over 117. Lets try out some problems...
What about 12x10? Well that equals 120 and since it goes over 117 that won't work.
What about 12x9? That equals 108. This is below 117. Since we know that Cara has 12 times more baseball cards than John has, we simply add 9 to 108 and it gives us 117 total baseball cards.
This means, John has 9 baseball cards.
