Answer:
$14 per lb
Step-by-step explanation:
Given:
- Brand Y = $18 / lb
- Special Blend = $17 / lb
Let x be the price per lb of brand X coffee
3 lbs of brand X coffee + 9 lb of brand Y coffee = 12 lbs of special blend
⇒ 3x + 9(18) = 12(17)
⇒ 3x + 162 = 204
⇒ 3x = 42
⇒ x = 14
Therefore, brand X costs $14 per lb
Answer:
30.5
Step-by-step explanation:
We know that ABCD is similar to EFGH so that means you can use a scale factor for them to figure out the rest of the side lengths.
25/12.5=2
12/6=2
Therefore the scale factor is two. Then we can use the numbers from the other side lengths which are 12 and divide by 2. Which gets you 6 for each remainder of the sides.
Then add them
12.5+6+6+6 = 30.5
P= 30.5
