How does g(t)=20.9t change over the interval from t=2 to t=3?
Marrrta [24]

slope = m = \cfrac{rise}{run} \implies \cfrac{ f(x_2) - f(x_1)}{ x_2 - x_1}\impliedby \begin{array}{llll} average~rate\\ of~change \end{array}\\\\[-0.35em] \rule{34em}{0.25pt}\\\\ g(t)= 20.9t\qquad \begin{cases} t_1=2\\ t_2=3 \end{cases}\implies \cfrac{g(3)-g(2)}{3-2}\implies \cfrac{20.9(3)~~ - ~~20.9(2)}{1} \\\\\\ 62.7~~ - ~~41.8\implies 20.9

A gift basket that contains jars of jam and packages of bread mix costs $45. There are 8 items in the basket. Jars of jam cost $
nordsb [41]

5 jars of jam and 3 packages of bread mix are in gift basket

<em><u>Solution:</u></em>

Let "x" be the number of jars of jam

Let "y" the number of packages of bread mix

Cost of 1 jars of jam = $ 6

Cost of 1 package of bead mix = $ 5

<em><u>There are 8 items in the basket</u></em>

Therefore,

number of jars of jam + number of packages of bread mix = 8

x + y = 8 ---------- eqn 1

<em><u>A gift basket that contains jars of jam and packages of bread mix costs $45</u></em>

Therefore, we frame a equation as:

number of jars of jam x Cost of 1 jars of jam + number of packages of bread mix x Cost of 1 package of bead mix = 45

x \times 6 + y \times 5 = 45

6x + 5y = 45 --------- eqn 2

<em><u>Let us solve eqn 1 and eqn 2</u></em>

From eqn 1,

x = 8 - y --------- eqn 3

<em><u>Substitute eqn 3 in eqn 2</u></em>

6(8 - y) + 5y = 45

48 - 6y + 5y = 45

y = 48 - 45

<h3>y = 3</h3>

<em><u>Substitute y = 3 in eqn 3</u></em>

x = 8 - 3

<h3>x = 5</h3>

Thus 5 jars of jam and 3 packages of bread mix are in gift basket
