Answer:

$61.10

Step-by-step explanation:

Original price: $120

50% of 120: $60

(You can either divide $120 in half or do:

120 * 0.50

= 60)

<em>The Helicopter would be $60 at 50% off.</em>

Next:

60 * 0.95 (0.95 comes from 1 - 0.05, which is the 5% off)

= 57

Finally, add the tax:

57 * 1.072

= 61.10

.45 * 120 = 54

.072 * 54 = 3.888

54 + 3.888 = 57.888= $57.89

The Pit BBQ food truck sells two combo packs of ribs and brisket. Combo A contains 10 oz of brisket and 16 oz of ribs and sells
GenaCL600 [577]

The maximum revenue is $700 which is at 16 combo A and 12 combo B.

<h3>Inequality</h3>

An inequality is an expression that shows the non equal comparison of two or more numbers and variables.

Let x represent the number of combo A and y represent the number of combo B, hence:

10x + 20y ≤ 400 (1)

Also:

x + y ≤ 28   (2)

The solution is at (16,12). Hence:

Revenue = 21.25 * 16 + 30 * 12 = $700

The maximum revenue is $700 which is at 16 combo A and 12 combo B.

If f(x) = 4x²-2 then f(-2) is​
klemol [59]
To find f(-2), substitute (-2) into x of the function f(x) = 4x^2-2
We get, f(-2) = 4(-2)^2 - 2
= (4*4)-2 = 16-2 = 14
Therefore, f(-2)=14.
