For this problem it just seems like all basic multiplaction

45 x 1.08 = 48.6

48.6 x 30 = 1,458

Your total answer is: 1,458

Hope this helps!

Suppose that the functions q and r are defined as follows.

Art [367]

Given:

The two functions are $q(x)=2x+2$ , $r(x)=x^2+1$

We need to determine the value of $(r \circ q)(-3)$ and $(q \circ r)(-3)$

Value of $(r \circ q)(-3)$ :

Let us determine the value of $(r \circ q)(-3)$

$(r \circ q)(x)=r[q(x)]$

$=r(2x+2)$

$=(2x+2)^2+1$

$=4x^2+8x+5$

Now, substituting x = -3, we get;

$(r \circ q)(-3)=4(-3)^2+8(-3)+5$

$=4(9)-24+5$

$=36-24+5$

$(r \circ q)(-3)=17$

Thus, the value of $(r \circ q)(-3)$ is 17

Value of $(q \circ r)(-3)$ :

Let us determine the value of $(q \circ r)(x)$

$(q \circ r)(x)=q[r(x)]$

$=q(x^2+1)$

$=2(x^2+1)+2$

$=2x^2+2+2$

$(q \circ r)(x)=2x^2+4$

Substituting x = -3, we get;

$(q \circ r)(-3)=2(-3)^2+4$

$=2(9)+4$

$(q \circ r)(-3)=22$

Thus, the value of $(q \circ r)(x)$ is 22.
