What is the price per lb of brand X coffee if 3 lb were mixed with 9 lb of brand Y coffee which costs $18/lb to make 12 lb of Ka
Georgia [21]

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

The balance owed on your credit card triples from $700 to $2100 in 12 months. If the balance is growing linearly then it would t
Fofino [41]

Answer:

If the balance is growing exponentially the balance after 45.4 months will be $44,925.94.

Step-by-step explanation:

The exponential growth equation is:

f(x)=700(1+0.096)^{x}

Compute the value of f (x) for <em>x</em> = 45.4 as follows:

f(x)=700(1+0.096)^{x}

       =700(1+0.096)^{45.4}\\\\=700\times (1.096)^{45.4}\\\\=700\times 64.1799181\\\\=44925.94267\\\\\approx 44925.94

Thus, if the balance is growing exponentially the balance after 45.4 months will be $44,925.94.
