Answer:
$ 1.2 and $ 0.7
Step-by-step explanation:
In this case we can solve it by means of a 2x2 system of equations, like this:
Let x is the value of clif bars
let y is the value of an apple
Thus:
4 * x + 2 * y = 6.2
5 * x + 3 * y = 8.1 => x = (8.1 - 3 * y) / 5
replacing, we are left with:
4 * ((8.1 - 3 * y) / 5) + 2 * y = 6.2
6.48 - 2.4 * y + 2 * y = 6.2
2.4 * y - 2 * y = 6.48 - 6.2
0.4 * y = 0.28
y = 0.28 / 0.4
y = 0.7
Now to calculate x:
x = (8.1 - 3 * 0.7) / 5
x = 1.2
So the value of clif bars is $ 1.2 and the value of an apple is $ 0.7
(fg)(x) = (3x + 6) (<span>2x^2)
</span>(fg)(x) = 6x^3 + 12x^2
